LETTER  OP  TRANSMITTAL. 


September,  1928. 

To  His  Excellency,  The  Honorable  C.  C.  Young, 
Governor  of  the  State  of  California. 
Sir  :  I  have  the  honor  to  herewith  transmit  Bulletin  No.  101  of  the 
State  Division  of  Mines  and  Mining,  being  the  annual  report  of  the 
statistics  of  the  mineral  production  of  California. 

The  remarkable  variety,  total  valuation,   and  wide  distribution  of 
many  of  our  minerals  revealed  herein  show   California's  importance 
as  a  producer  of  commercial  minerals  among  the  states  of  the  Union. 
Respectfully  submitted. 

Walter  W.  Bradley, 
State  Mineralogist.

INTRODUCTION 


It  is  tlie  endeavor  of  the  staff  of  tlie  State  Mining  Bureau    (now 
Division  of  ]\Iines  and  Mining'  of  the  State  Department  of  Natural 
Resources),  in  these  annual  reports  of  the  mineral  industries  of  Cali- 
fornia, to  so  compile  the  statistics  of  production  that  they  will  be  of 
actual  use  to  producers  and  to  those  interested  in  the  utilization  of  the 
mineral  i)roducts  of  our  state,  while   at  the  same  time  keeping  the 
individual's  data  confidential.  In  additicm  to  the  mei-e  figures  of  out- 
put, we  have  included  descriptions  of  the  uses  and  characteristics  of 
many  of  the  materials,  as  well  as  a  brief  mention  of  their  occurrences. 
The  compilation  of  accurate  and  dependable  figures  is  an  extremely 
j    difficult  undertaking,  and  the  State  Mineralogist  takes  the  opportunity 
of  here  expressing  his  appreciation  of  the  cooperation  of  the  producers 
i   in  making  this  work  i:)ossible.     A  fuller  appreciation  of  the  value  of 
j  early  responses  to  the  requests  sent  out  in  January  will  result  in  earlier 
ll  completion  of  the  manuscript.     Statistics  lose  much  of  their  value  if 
;  their  i)ublication  is  unnecessarilv  delaved. 

Some  of  the  data  relative  to  properties  and  uses  of  many  of  the 
minerals  herein  described  are  repeated  from  preceding  reports,  as  it 
is  intended  that  this  annual  statistical  bulletin  shall  be  somewhat  of  a 
compendium  of  information  on  California's  commercial  minerals  and 
llieir  utilization.

MINERAL  INDUSTRY,  CALIFORNIA,  1927 


DATA    COMPILED    FROM    DIRECT    RETURNS    FROM    PRO- 
DUCERS IN  ANSWER  TO  INQUIRIES  SENT  OUT  BY  THE 
CALIFORNIA   STATE   DIVISION   OF   MINES   AND 
MINING,     FERRY    BUILDING,     SAN 
FRANCISCO,    CALIFORNIA 


CHAPTER   ONE 

The  total  value  of  tlie  mineral  output  of  California  for  the  year  1927 
was  $366,781,394,  being  a  decrease  of  $83,549,462  under  the  1926  total 
of  $450,330,856.  There  were  fifty-eight  different  mineral  substances, 
exclusive  of  a  segregation  of  the  various  stones  grouped  under  gems; 
and  all  of  the  fifty-eight  counties  of  the  state  contributed  to  the  list. 

As  revealed  by  the  data  following,  the  salient  features  of  1927  com- 
pared with  the  preceding  year  were :  A  large  drop  in  the  value  of 
petroleum  in  an  amount  greater  than  the  net  decrease  in  the  grand  total 
for  all  substances,  being  only  partly  offset  by  increases  in  other  items. 
Material  advances  were  made  by  borates,  cement,  potash,  natural  gas, 
granite,  limestone,  quicksilver,  sandstone,  and  soda.  Decreases  were  reg- 
istered by  copper,  zinc,  miscellaneous  stone,  brick,  lead,  salt,  and  silver. 
Petroleum  showed  a  decrease  in  value  of  $84,811,179,  although  there 
was  an  increase  from  224,637,281  barrels  to  231,195,774  barrels.  This 
was  due  to  a  sharp  cut  in  the  price  of  crude  oil,  mainly  for  grades  over 
20°  Baume,  effective  April  16,  1927.  There  were  a  number  of  other 
minor  variations,  the  result  being  a  decrease  in  the  totals  of  the  fuels 
and  metals  groups,  while  all  other  groups  showed  increases. 

Of  the  metals,  titanium  was  added  to  the  list,  being  the  first  year 
of  any  record  of  its  production  in  commercial  quantity  in  California; 
quicksilver  increased  from  5892  flasks  worth  $516,382  to  6488  flasks 
worth  $714,418,  this  being  accounted  for  by  the  advanced  price  received 
by  the  producers.  In  1926  they  received  $87.64  and  in  1927,  $116.94 
per  75-pound  flask.  Copper  decreased  from  33,521,544  pounds  worth 
$4,693,014  to  27,350,316  pounds  worth  $3,582,885 ;  gold  from  $11,923,- 
481  to  $11,671,018;  lead  from  8,067,873  pounds  worth  $645,429  to 
2,748,440  pounds  worth  $173,151;  silver  from  2,022,460  fine  ounces 
worth  $1,262,015  to  1,620,242  fine  ounces  worth  $918,677;  and  zinc 
from  20,447,559  pounds  worth  $1,533,568  to  8,625,004  pounds  worth 
$552,000.  The  decrease  in  copper,  lead  and  zinc  was  due  to  a  drop  in 
the  market  prices,  while  the  gold  and  silver,  by-products  of  these  ores, 
account  for  the  decreases  in  the  total  gold  and  silver  figures.     Though 


12  MINERAL    INDUSTRY    OF    CALIFORNIA 

tlie  gold  yield  decreased  in  value,  California  continues  in  the  lead,  and 
in  1927  accounted  for  approximately  26  per  cent  of  the  gold  output  of 
the  United  States. 

Of  the  structural  group :  Cement  advanced  from  13,797,173  barrels 
valued  at  $25,269,678  to  14,661,783  barrels  at  $26,474,935,  though  the 
avej-age  price  per  barrel  dropped  from  $1.84  to  $1.80;  granite  increased 
in  value  from  $655,332  to  $3,398,443,  and  sandstone  from  $17,500  to 
$205,400;  brick  and  hollow  building  tile  dropped  from  a  valuation  of 
$7,026,124  to  $6,516,077,  and  miscellaneous  stone  from  $19,859,873  to 
$18,912,994;  of  the  remaining  minerals  in  this  group  there  were  no 
material  changes.  Of  the  industrial  minerals  there  were  a  number  of 
fluctuations  with  a  general  trend  of  increasing  production  and  value. 
The  important  changes  were :  i)otterv  clav  with  an  increase  from 
797,461  tons  valued  at  $806,509  to  867,419^  tons  and  $872,661;  lime- 
stone from  108,795  tons  valued  at  $367,501  to  899,790  tons  and  $663,- 
957.  Of  the  saline  group,  borates  showed  an  increase  from  47,605  tons 
valued  at  $1,625,298  to  72,462  tons  at  $3,043,260;  potash,  32,884  tons 
valued  at  $812,285  to  67,340  tons  and  $1,952,852;  and  salt  showed  a 
decrease  from  311,761  tons  valued  at  $1,124,978  to  263,028  tons  and 
$639,127. 

The  figures  of  the  State  Divi.sion  of  Mines  and  Mining  are  made  up 
from  reports  received  direct  from  the  producers  of  the  various  minerals. 
Care  is  exercised  in  avoiding  du])lication,  and  any  error  is  likely  to  be 
on  the  side  of  undei--  rather  than  over-estimation. 

California  yields,  commercially,  a  greater  number  and  variety  ofj 
mineral  products  than  anj''  state  in  the  United  States,  and  probably] 
more  than  any  other  equal  area  elsewhere  on  the  earth.     The  total! 
annual  value  of  her  output  has  been  surpassed  by  not  more  than  four' 
or  five  others,  and  those  usually  the  great  coal  states  of  east  of  the 
IMississippi.     More  recently  California  has  been  placed  second  to  Penn- 
sylvania, the  leader.     California  was  for  many  years  the  sole  domestic 
source  of  borax,  chromite  and  magnesite,  and  in  which  we  still  lead. 
"We  lead  all  other  states  in  the  production  of  gold,  quicksilver,  and 
platinum ;  and  have  alternated  in  the  lead  with  Colorado  in  tungsten, 
and  with  Oklahoma  in  petroleum. 

The  mineral  industries,  not  only  in  California,  but  throughout  the 
country,  have  reached  quite  a  different  phase  from  that  of  the  old 
gold-rush  days  more  than  fifty  years  ago.  A  broader  and  more  inti- 
mate status  has  been  attained,  touching  practically  every  avenue  of 
domestic  and  commercial  endeavor.  As  quoted  in  a  former  report^  of 
the  freight  handled  by  the  railroads  of  the  country,  the  products  of 
the  mines  represent  51.33  per  cent.  While  gold,  in  which  California 
still  leads  the  United  States,  is  still  important,  other  metals  and  even 
nonmetals  have  superseded  it  in  annual  value.  The  greatest  commer- 
cial developments  proportionately  in  California  in  recent  years  have 
taken  place  among  the  industrial  and  structural  minerals,  not  to  men- 
tion petroleum,  which  leads  all  others  in  value.  This  introduces  a  new 
factor  which  requires  study  and  attention — that  of  marketing.  The 
gold  miner  could,  and  still  does,  take  his  metal  to  the  mint  and  receives 

'  Cal.  State  Min.  Bur.,  Bulletin  !)6,  p.  12,  1925.

its  equivalent  in  the  'coin  of  tlie  realm';  and  he  knows  from  day  to 
day  and  year  to  year,  Avithout  variation,  just  how  much  each  ounce  of 
gold  will  bring  in  that  coin,  though  its  equivalent  in  other  commodities 
varies  according  to  economic  conditions.  Marketing  and  competition, 
however,  are  vital  factors  in  the  industrial  and  structural  groups.

STATISTICS    OF    ANNUAL    PRODUCTION

Total   Mineral  Production  of  California,  by  Years. 

The  following  tabulation  gives  the  total  value  of  mineral  production 
of  California  by  years  since  1887,  in  which  year  compilation  of  such 
data  by  the  State  Mining  Bureau  (now  Division  of  Mines  and  ]\Iining) 
began.  At  the  side  of  these  figures  the  writer  has  placed  the  values  of 
the  most  important  metal  and  non-metal  items — gold  and  petroleum. 

In  the  same  period  copper  made  an  important  growth  beginning  with 
1897  following  the  entry  of  the  Shasta  County  mines,  and  more  recently 
Plumas  County.  Cement  increased  rapidly  from  1902,  while  crushed 
rock,  sand  and  gravel  as  a  group  parallels  the  cement  increase.  Quick- 
silver has  been  up  and  down.  IMineral  water  and  salt  have  always  been 
important  items,  but  the  values  fluctuate.  Borax  has  increased  mate- 
rially since  1896.  War-time  increases,  1915-1918,  were  shown  by 
chromite,  copper,  lead,  magnesite,  manganese,  silver,  tungsten  and  zinc. 
Most  of  these,  except  silver,  have  since  declined,  though  structural 
materials  and  copper  increased  in  1920-1924,  also  lead  and  magnesite 
in  1923;  lead  and  zinc  in  1925;  zinc  in  1926,  with  silver  declining;  an 
increase  in  quicksilver  in  1927,  Avith  a  decline  in  all  other  metals.

COAL 

Bibliography:  State  Mineralogist  Reports  VII,  XII-XV  (iuc), 
XVII,  xiX-XXI  (inc.).  U.  S.  Geol.  Surv.,  Bulletins  285,  316, 
431,  471,  581 ;  Ann.  Kept.  22,  Pt.  III. 

The  coal  production  in  California  for  1927  was  limited  to  Amador 
County.  This  was  consumed  by  a  local  market  and  also  on  the  property 
for  camp  purposes,  power  and  forge,  to  carry  on  regular  operation 
and  development  work. 

, Total  Coal  Production  of  California. 

The  very  considerable  output  of  coal  in  the  years  previous  to  1883 
was  almost  entirely  from  the  Mount  Diablo  district,  Contra  Costa 
County.  Later  the  Tesla  mine  in  Corral  Hollow,  Alameda  County,  was 
an  important  producer  for  a  few  years.  Stone  Canyon,  Monterey 
County,  was  also  an  important  producer  for  a  short  time,  and  there 
has  been  some  coal  shipped  from  properties  in  Amador,  Fresno,  Orange, 
Riverside  and  Siskiyou  counties.  The  following  tabulation  gives  the 
annual  tonnages  and  values,  according  to  available  records :

HEPTANE 

lie-ptane  was  added  to  the  list  of  hydrocarbons  this  year.  There 
was  a  production  reported  as  a  by-product  of  bromine  recovery  from 
bittern  water  of  San  Diego  County. 

Heptane  is  used  as  a  solvent  of  alkalies  in  vegetable  oils,  an  antiseptic, 
a  starter  for  other  organic  compounds,  and  as  an  ideal  fuel.  The 
reason  for  its  value  in  these  uses  is  its  definite  chemical  composition 
and  its  l)oiling  point  at  98°  C,  just  under  the  boiling  point  of  water. 

NATURAL  GAS 

Bibliography:  State  Mineralogist  Reports  VII,  X,  XII,  XIII,  XIV. 
Bulletins  3,  16,  19,  69,  73,  89.  Monthly  Summary,  Oil  &  Gas 
Supervisor,  Dec,  1919;  Aug.,  1922;  Mar.,  1923;  Mar.  and  Apr., 
1926. 

Statistics  on  the  production  of  natural  gas  in  California  are  in  a  con- 
siderable degree  difficult  to  arrive  at,  as  much  of  it  that  is  utilized 
directly  at  the  wells  for  heating,  lighting,  and  driving  gas  engines  is 
not  measured.  Hence,  it  is  necessary  to  approximate  the  output  of 
many  of  the  operators  in  tlie  oil  fields,  estimated  on  the  number  of 
lights,  and  on  the  number  and  horsepower  of  gas  engines  and  steam 
boilers  thus  operated.  The  figures  here  given  are  for  gas  utilized 
locally  and  also  that  sold  for  distribution  to  consumers ;  and  we  consider 
are  not  over-estimated,  particularly  in  the  six  oil-producing  counties. 
It  must  be  remembered  that  some  of  our  important  oil  fields  are 
removed  manj-  miles  from  the  site  of  any  other  industry,  and  that  the 
gathering  of  small  amounts  of  gas  and  transporting  it  for  any  consider- 
able distance  may  not  always  be  profitable,  nor  is  it  often  possible  to 
have  pipe-line  facilities  available  to  handle  the  gas  accompanying  the 
early  gas  production  in  newly  developed  fields.  Wherever  feasible, 
casing-head  gas  is  used  in  driving  gas  engines  for  pumping  and  drill- 
ing, and  in  firing  the  boilers  of  steam-driven  plants. 

The  most  notable  gas  developments  in  California  have  been  in  the 
Elk  Hills  and  Buena  Vista  Hills  in  Kern  County,  northeast  of  the 
Midway  district ;  in  the  oil  fields  in  the  Los  Angeles  basin,  Los  Angeles 
and  Orange  counties;  and  more  recently  in  Ventura  County. 

Production  and   Value. 

There  is  rather  a  wide  variation  in  prices  quoted  for  natural  gas 
because  a  considerable  part  is  used  directly  in  the  field  for  driving  gas 
engines  and  firing  boilers,  and  is  therefore  not  measured  nor  sold. 
Such  companies  as  have  placed  a  valuation  on  the  gas  that  was  thus 
used  in  1927  gave  from  3^  to  25^'  per  1000  cu.  ft.,  at  the  well.  From; 
the  totals  shown  in  the  tabulation  following  herein,  the  average  value 
for  all  fields  in  1927  works  out  at  approximately  9. If/-.    Approximately 
7000  cu.  ft.  of  gas  is  equal  to  one  barrel  of  oil  in  heating  value,  and  is  ^ 
so  accounted  for  by  many  operators.     In  driving  gas  engines,  about 
4000  cu.  ft.  per  24  hr.  are  consumed  by  a  25-h.p.  engine,  and  63,700 
cu.  ft.  per  day  for  heating  a  70-h.p.  steam  boiler,  which  figures  have' 
been  utilized  in  compiling  this  report,  in  those  cases  where  gas  was  not: 
metered,

smaller  quantities  of  natural  gas,  but  there  was  a  larger  quantity  of 
natural  gas  gasoline  treated. 


Natural  Gas  Production  in  California,  Since  1888. 

The  production  of  natural  gas  in  California  by  years  .since  1888  is 
given  in  the  following  table.  The  first  economic  use  of  natural  gas  in 
California  was  from  the  famous  Court  House  well  at  Stockton,  bored 
in  1854-1858.  Beginning  about  1883  and  for  several  succeeding  years, 
a  number  of  gas  wells  were  brought  in  around  Stockton.  Natural  gas 
was  known  in  a  number  of  other  localities,  and  occasionally  utilized  in 
a  small  way,  notably  at  Kelseyville  in  Lake  County,  and  in  Humboldt 
County  near  Petrolia  and  Eureka,  but  there  are  no  available  authentic 
records  of  amounts  or  values  previous  to  the  year  1888.  The  most 
important  developments  in  the  commercial  production  of  natural  gas 
have  been  coincident  with  developments  in  the  oil  fields,  by  utilizing 
the  casing-head  gas  as  well  as  that  from  dry-gas  wells.

Gasoline  from    Natural   Gas. 

More  or  less  gas  usually  accompanies  the  petroleum  in  the  oil  fields, 
and  such  gas  carries  varying  amounts  of  gasoline.  A  total  of  142  plants 
Avere  in  operation  in  1927  recovering  gasoline  by  compression  or  absorp- 
tion from  this  'casing-head'  gas.  After  the  gasoline  is  extracted  the 
remaining  'dry  gas'  .so  far  as  practicable  is  taken  into  pipe  lines,  by 
Avhich  it  is  distributed  to  consumers,  both  domestic  and  commercial. 

In  certain  of  the  oil  fields,  some  of  the  casing-head  gasoline  is  obtained 
as  an  incidental  product  to  the  compressing  of  the  natural  gas  prelim- 
inary to  its  transmission  to  consuming  centers  through  the  gas  pipe 
lines.  Some  concerns  market  the  casing-head  gasoline  separately,  others 
blend  it  with  distiller}^  gasoline,  while  others  turn  it  into  the  oil  pipe 
lines  thus  mixing  this  high-gravity  gasoline  with  the  crude  oil  for  trans- 
portation to  the  i-efinery  where  it  is  later  regained.  A  total  of  489,- 
798,683  gallons  of  casing-head  gasoline  valued  at  $45,700,264  from  all

well.  This  total  of  quantity  is  compiled  from  the  monthly  production 
reports  filed  by  the  operators  with  the  State  Oil  and  Gas  Supervisor, 
to  which  have  been  added  figures  for  the  output  of  a  number  of  small 
operators  in  the  old  Los  Angeles  City  Field  not  under  the  jurisdiction 
of  the  Supervisor. 

The  question  of  th(>  value  of  the  crude  oil  yield  at  the  well  is  a  diffi- 
cult one  to  settle  with  exactitude  principally  because  a  large  part  of 
the  output  is  not  sold  until  after  refining.  The  large  refiners  are  also 
large  ])roducers  of  crude  oil  which  they  send  direct  from  well  to  plant, 
hence  much  of  the  crude  oil  is  not  sold  as  such.  The  values  used  in  the 
statistical  reports  of  the  State  ]\Iining  Bureau  since  1914  have  been 
derivfd  from  averages  of  actual  sales  of  crude  oil  of  all  grades  in  each 
field  of  the  state,  and  these  averages  applied  to  the  total  yield  of  the 
respective  fields.  This  we  feel  is  a  safer  measure  of  commercial  values 
than  market  quotations,  because  quotations  do  not  always  mean  sales. 
This  is  particularly  true  on  a  rising  or  a  falling  market. 

Features  of  1927. 

The  noteworthy  features  of  the  year  1927  in  the  oil  industry  were 
increa.sed  output  in  Orange,  Santa  Barbara  and  Ventura  counties  and 
decreases  in  all  other  counties.  There  were  sharp  cuts  in  the  price  of 
crude  oil  in  all  grades  over  20°  Baume,  making  the  value  in  all  counties 
less  than  in  1926. 

Summarizing  the  data  for  the  year,  the  State  Oil  and  Gas  Supervisor  ^ 
presented  the  following  figures  : 

"The  total  production  of  oil  in  the  .state  for  the  last  six  months  of  1927  was 
114,891,618  barrels  of  oil  and  58,897,272  barrels  of  water.  The  production  of  oil  for 
the  year  1927  was,  therefore,  231,045,773  barrels,  an  increase  of  6,522,349  barrels 
over  that  of  1926.  The  increased  production  came  from  the  Seal  Beach  and  Hunt- 
ington Beach  fields  and  while  the  Ventura  field  increased  over  3,000,000  barrels, 
there  was  a  nearly  equal  decrease  in  the  fields  of  Kern  County. 

"The  production  of  oil  for  the  second  half  of  1927  was  1,262,537  barrels  less  than 
for  the  first  half.  Water  production  increased  3,290,754  barrels  during  the  .same 
period.     *      *      * 

"The  estimated  closed-in  production  was  increased  during  1927  from  61,314  barrels 
daily  in  January  to  a  maximum  of  89,442  barrels  daily  in  May  and  decreasing  to 
77,107  barrels  daily  in  December.      *      *      * 

"Storage  and   Price  Changes. 

"The  total  crude  oil  and  refined  petroleum  in  storage  in  Pacific  coast  territory  at 
the  end  of  1927  was  137,395,067  barrels,  according  to  the  American  Petroleum 
Institute.  The  decrease  in  storage  during  the  year  amounted  to  8,217,109  barrels 
compared  with  a  decrease  of  11,704,133  barrels  during  1926.  The  total  amount  of 
crude  and  refined  oil  shipped  to  eastern  ports  during  1927  was  33,080,000  barrels,  or 
42,000  barrels  more  than  the  1926  shipments. 

"On  April  1,  1927,  prices  of  crude  oil  of  15  degrees  gravity  and  above  in  some 
fields,  and  of  19  degrees  gravity  and  above  in  other  fields,  were  lowered. 

"Drilling  and   Development. 

"During  1927,  1263  wells  were  reported  to  the  State  Oil  and  Gas  Supervisor  as 
ready  to  drill  as  compared  with  1268  new  wells  in  1926.  Five  new  fields  were  dis- 
covered in  1927,  most  of  which  are  relatively  unimportant.  These  fields  were  the 
Alamitos  dome  of  the  Seal  Beach  field,  the  Potrero  field  in  Los  Angeles  County,  the 
Rincon  field  in  Ventura  County,  the  Goleta  field  in  Santa  Barbara  County,  and  the 
Round  Mountain  field  in  Kern  County.  Of  these,  the  most  important  was  the  exten- 
sion of  the  Seal  Beach  field,  which  contributed  much  to  the  1927  production.  The 
productive  possibilities  of  the  Rincon,  Potrero  and  Round  Mountain  fields  had  not 
been  determined  at  the  end  of  the  year.  The  Goleta  field  produced  a  small  amount 
of  high  gravity  oil  and  apparently  reached   lis  limit." 

During  1927  there  was  a  small  production  of  high-grade  petroleum 
from  Colusa  County.     This  was  marketed  for  medicinal  purposes.

For  several  years  previous  to  1919,  the  state  average  value  per  barrel 
at  the  well  for  crude  oil  as  determined  by  the  statistical  returns  wa.s 
noted  to  practically  coincide  with  the  quotations  during  the  same  years 
for  23°  gravity  oil  in  the  San  Joaquin  Valley  fields.  In  1919  and  since, 
the  average  values  have  worked  out  at  figures  corresponding  to  quota- 
tions up  to,  in  one  year  as  high  as  28°  oil,  due  to  the  large  yield  of 
high-gravity  oils  from  the  new  fields  in  the  Los  Angeles-Orange  counties 
area. 


TOTAL   PETROLEUM   PRODUCTION    OF    CALIFORNIA 

The  presence  of  oil  seepages  and  springs  in  Los  Angeles  and  Ventura 
counties  was  known  and  utilized  in  a  small  way  early  in  the  history  of 
California.  Some  also  was  shipped  to  refineries  at  San  Francisco  from 
Santa  Barbara  and  Humboldt  counties.     In  the  light  of  present-day

STATISTICS   OF    ANNUAL   PRODUCTION  25 

developments,  the  following  reference  to  the  previous  year's  production 
of  oil  and  its  future  prospects  as  expressed  by  the  San  Francisco  Bulle- 
tin of  January  8,  1866,  is  strikingly  prophetic  even  though  skeptical : 

"It  is  possible  that  the  small  quantity  received  (40,000  or  50,000  gallons  in  1865) 
may  be  the  forerunner  of  many  millions  which  will,  at  some  future  time,  lubricate 
the  wheels  of  commerce  and  set  a  trade  at  work  excelling  in  variety  any  that  has 
thus  far  been  known  on  this  coast.  At  present,  however,  we  admit  to  being  a  little 
skeptical  about  the  assumption  of  the  astute  Professor  Silliman  that  California  will 
be  found  to  have  more  oil  in  its  soil  than  all  the  whales  in  the  Pacific  Ocean." 

According  to  Hanks,^  in  1874  production  amounted  to  36  bbl.  per 
day  from  natural  flows  in  Pico  Canon  (Newhall),  and  at  Sulphur 
Mountain  (Ventura  County),  the  oil  being  of  32°  gravity  average. 

"  "Work  was  commenced  in  Pico  Canyon  in  1875  by  drilling  three  shallow  wells  with 
spring  pole,  all  of  which  yielded  oil  at  depths  of  from  90  to  250  feet.  Actual  work 
of  development  commenced  with  steam  machinery  in  1877.'' 

In  1877  Pico  averaged  40-50  bbl.  daily,  and  Ventura  80  bbl.  daily. 
In  1878,  there  was  some  production  (@  60  bbl.  per  day,  for  a  time) 
from  wells  in  Moody  Gulch,  near  Los  Gatos,  Santa  Clara  County,  the  oil 
being  of  46°  Baume. 

The  first  wells  in  the  Coalinga,  Fresno  County,  and  Summerland, 
Santa  Barbara  County,  fields  were  drilled  in  1890,  but  Coalinga  did  not 
make  its  influence  felt  conspicuously  on  the  state's  annual  output  until 
1903.  The  Summerland  yield  never  has  been  large.  The  Salt  Lake 
field  near  Los  Angeles  began  production  in  1894  and  in  1897  reached 
over  a  million  barrels  annually. 

In  the  Kern  Countv  fields,  the  first  well  was  drilled  in  Sunset  in 
1891,  Midway  in  1900"^  McKittrick  in  1892,  Kern  River  in  1899.  The 
Sunset-Midway  district  attained  a  yield  of  over  4,000,000  bbl.  in  1909, 
and  over  20,000,000  bbl.  in  1910.  Kern  River  field  produced  over 
3,000,000  bbl.  in  1901. 

The  first  well  in  the  Santa  Maria-Lompoc  group,  Santa  Barbara 
Countv,  was  drilled  in  1901,  and  the  district  advanced  to  a  yield  of 
over  3,000,000  bbl.  annually  in  1905. 

The  Whittier-Fullerton  field  in  Los  Angeles  and  Orange  counties 
became  an  important  factor  in  1902.  The  Montebello  field,  Los  Angeles 
County,  was  the  conspicuous  addition  in  1918-1919 ;  and  Elk  Hills, 
Kern  County,  with  Huntington  Beach  and  Richfield,  Orange  County, 
in  1920.  In  1921,  the  new  fields  added  were  Long  Beach  and  Santa  Fe 
Springs,  Los  Angeles  County;  in  1922,  Torrance  field  in  Los  Angeles 
County,  and  Wheeler  Ridge  field  in  Kern  County ;  but  the  production 
from  the  large  number  of  new  wells  started  in  these  new  Los  Angeles 
County  fields  did  not  reach  its  peak  until  August  and  September,  1923. 
Dominguez  (Compton)  came  in  during  1923;  followed  by  Rosecrans 
and  Inglewood  in  1924.  Ventura  recorded  important  additions  to  its 
producing  area  in  1925  and  1926.  Seal  Beach,  Orange  County,  and 
Mt.  Poso,  Kern  County,  were  the  new  fields  added  in  1926 ;  Round 
Mountain,  Kern  County,  and  Rincon,  Ventura  County,  were  the  new 
fields  added  in  1927.

[Specific   Gravity  of  Oils   Produced. 


The  proportion  of  heavy  and  light  oil  produced  in  the  various  fields 

lis  shown  in   Table   E,   following,   for  M^hich   we   are   indebted  to   the 

[Standard  Oil  Company.    Under  present  practice,  oil  below  18°  Baume 

lay  be  considered  as  largely  refinable  for  fuel  and  lubricants,  while 

Jthe  lighter  oils  yield  varying  amounts  of  the  higher  refined  products 

nth.  corresponding   proportions   of   residuum   and   fuel   oil.     Specific 

gravities  in  California  range  from  8°  Baume  in  the  Casmalia  field. 

[Santa  Barbara  County,  to  56°  Baume  in  Ventura  County. 

California  crude  oils  are  all  essentially  of  asphalt  base,  with  a  few 
lotable  exceptions.  In  the  following  localities  are  wells  yielding  crudes 
containing  both  asphalt  and  paraffine  constituents :  Oil  City  field,  Coal- 
inga ;  a  few  deep  wells  in  East  Side  field,  Coalinga ;  a  considerable  part 
of  the  Ventura  County  fields ;  Western  Minerals  area,  south  of  Mari- 
copa ;  Wheeler  Ridge,  Kern  County.

*  Formerly  reported  as  Whittier-Fullerton. 

As  ]n-evioiisly  noted  by  Bradley,^  a  decided  change  has  taken  place 
in  the  relative  proportions  of  light  and  heavy  crudes  produced  in  Cali- 
fornia since  1910,  taking  18°  Baume  as  the  dividing  line.  This  subject 
has  also  been  covered  in  detail  and  with  charts,  by  Collom  and  Barnes." 

A  marked  drop  took  place  in  the  low-gravity  yield  from  1910  to  and 
including  1914.  From  1914,  it  remained  almost  stationary,  with  a 
slight  drop  in  1921,  while  the  high-gravity  yield  has  increased  at  a 
rapid  rate  since  1915.  The  proportions  have  been  reversed  from 
approximatelv  75%  low— 25%  high  in  1914  to  25%  low— 75%  high  in 
1921  ;  10%  low— 90%  high  in  1923;  14%  low— 86%  high  in  1924-1927. 

This  has  been  an  important  factor  in  its  effect  upon  the  average 
price  i)er  barrel  of  the  state's  output  in  these  years,  as  well  as  its  effect 
upon  tlie  relative  situation  between  production  and  consumption.  It 
luus  been  a  fortunate  development,  in  view  of  the  increased  demand  for 
refinery  products  (gasoline  in  particular). 

Oil   in   'Storage.' 

Field,  refinery,  pipe-line,  and  tank-farm  .stocks  of  crude  and  refined 
products  in  the  Pacific  Coast  territory  totaled  137,395,067  barrels^ 
December  31,  1927,  compared  with  145,612,176  barrels  on  December 
31,  1926.    The  total  decrease  in  stock  for  the  year  was  8,217,109  barrels.

Operating   Data. 

The  followiug  tabulation  (Table  P)  is  compiled  from  data  published 
by  the  Department  of  Petroleum  and  Gas,^  semiannually,  and  here  com- 
bined to  show  the  entire  year's  operations  for  all  fields.  The  districts 
are  the  geographical  subdivisions  as  administered  by  the  Department, 
and  Avhich  are  outlined  on  the  accompanying  map. 

It  Avill  be  noted  that  the  state  average  yield  of  oil  per  well  per  day 
was  62.0  barrels  for  the  first  six  months  of  1927  and  59.6  barrels  for 
the  second.  This  is  somewhat  higher  than  the  figure  of  54.1  barrels 
average  for  December  derived  from  American  Petroleum  Institute  data 
as  shown  in  Table  D,  on  a  preceding  page,  due  in  part  at  least,  to  the 
fact  that  the  latter  is  on  a  full-time  basis,  whereas  the  Bureau  figures 
alloAV  for  shut-down  time.

Financial  and  Operating  Conditions  of  California  Oil   Fields,  1927. 


Financial  results  of  the  oil  business  during  1927  are  shown  by  the 
following  tables.  The  features  worthy  of  mention  are :  (1)  There  were 
487  operating  companies  in  1927  Avith  a  total  capitalization  value  of 
$1,272,555,286  (see  Table  G),  which  was  a  decrease  in  the  number  of 
companies  from  491  in  1926  with  an  increased  capitalization  from 
$1,241,242,935.  (2)  A  total  increase  in  dividends  was  paid,  with  all 
counties  showing  an  increase  over  their  1926  dividends,  with  the  excep- 
tion of  Fresno  and  Santa  Barbara  (see  Table  H).  (3)  An  increase  in 
the  barrels  per  well  per  day  (see  Table  I)  in  Santa  Barbara  and 
Ventura  counties,  with  a  decrease  in  all  other  counties  and  a  marked 
drop  in  Los  Angeles  County.  (4)  A  slightly  less  operating  cost  in 
all  counties  with  the  exception  of  Los  Angeles  and  Orange. 

With  reference  to  Table  I,  it  should  be  noted  that  although  it  lacks 
data  from  the  larger  operators  who  have  refineries  and  with  interests 
in  more  than  one  field,  yet  the  data  given  are  of  economic  value  and 
interest  in  that  tliey  indicate  the  conditions  prevailing  among  the 
smaller  companies  and  operators. 

Operating  cost  per  well  is  not  always  lower  for  the  dividend  com- 
panies than  others.  Profitable  operations  seem  to  depend  generally 
upon  large  wells,  high-grade  oil,  and  proximity  to  market.  Price  and 
profits  have  iLsually  been  greater  in  the  Los  Angeles-Orange-Ventura 
fields  than  in  others,  doubtless  largely  due  to  the  proximity  to  market 
and  higher  grades  of  oil.  Crude  oil  testing  as  high  as  56°  Baume  is 
obtained  from  some  of  the  Ventura  wells.

CHAPTER    THREE 

METALS 

Bibliography :  Reports  of  State  Mineralogist  I-XXII  (inc.)-  Bul- 
letins 5,  6,  18,  23,  27,  36,  50,  57,  76,  78,  85,  92,  95.  Spurr  and 
Wormser,  "Marketing  of  Metals  and  Minerals."  See  also  under 
each  metal. 

The  total  value  of  metals  produced  in  California  during  1927  was 
$17,990,841.  The  chief  of  these  is,  and  always  has  been,  gold,  followed 
by  copper,  silver,  quicksilver,  zinc,  tungsten,  lead,  titanium,  iron  ore 
and  platinum.  There  was  a  small  output  of  antimony.  There  was  no 
production  of  arsenic,  cadmium,  molybdenum,  nor  tin,  which  have  in  the 
past  been  on  the  active  list.  Deposits  of  ores  of  nickel  and  vanadium 
have  also  been  found  in  the  state ;  although  there  has  yet  been  no  com- 
mercial output  of  them.  The  above-noted  total  of  this  group  is  a  net 
decrease  of  $2,937,903  from  the  1926  total  of  $20,928,744,  due  mainly 
to  decreases  registered  by  copper,  gold  and  silver,  in  spite  of  an 
increase  by  quicksilver. 

California  leads  all  states  in  the  Union  in  her  gold  production  and 
is  credited  with  approximately  26%  of  the  nation's  yield  in  1927.  The 
precious  metal  is  widely  distributed  through  the  state.  Thirty-four  of 
the  fifty-eight  counties  reported  an  output  in  1927  from  either  mines 
or  dredges. 

Copper,  which  is  second  in  importance  among  the  metals  of  the 
state,  occurs  in  the  following  general  districts :  the  Shasta  County  belt, 
which  has  been  by  far  the  most  important ;  the  Coast  Range  deposits, 
extending  more  or  less  continuously  from  Del  Norte  in  the  north  to  San 
Luis  Obispo  County  in  the  south ;  the  Sierra  Nevada  belt,  starting  in 
Plumas  and  running  in  a  general  southerly  and  southeasterly  direction 
through  the  Mother  Lode  counties  and  ending  in  Kern;  the  eastern 
belt  in  Mono  and  Inyo  counties,  and  the  southern  belt  in  San  Bernar- 
dino, Riverside  and  San  Diego  counties. 

Silver  is  not  generally  found  alone  in  the  state,  except  notably  in  the 
Rand  district,  San  Bernardino  County ;  but  is  associated  to  a  greater  or 
less  extent  with  gold,  copper,  lead  and  zinc. 

Quicksilver  has  for  many  years  been  one  of  the  state's  staple  prod- 
ucts and  California  has  supplied  approximately  75%  of  the  nation's 
output  of  this  metal. 

Tungsten  is  found  in  but  few  other  localities  of  importance  in  the 
United  States. 

Large  deposits  of  iron  ore  have  long  been  known  in  several  sections 
of  the  state,  but  for  various  economic  reasons  this  branch  of  the  mineral 
industry  thus  far  has  made  only  slight  progress  on  the  Pacific  Coast. 

Titanium  is  associated  with  some  of  California's  iron  deposits.  This 
mineral  is  widely  distributed  through  the  United  States,  but  the 
deposits  of  this  state  are  among  the  few  that  are  considered  of  com- 
mercial importance. 

Although  the  United  States  is  a  large  consumer  of  certain  metals, 
in  fact  the  largest  particularly  of  chromium  and  tin,  our  production 
from  domestic  sources  is  deficient.    We  have  large  reserves  of  low-grade

To  date  there  has  been  no  commercial  production  of  aluminum  ore 
in  California  Only  a  single  authenticated  occurrence  of  bauxite  has 
thus  far  been  noted  in  this  state,  being  in  Riverside  County,  southeast 
of  Corona,  but  as  yet  undeveloped. 

Minerals  containing  aluminum  are  abundant,  the  most  widely  dis- 
tributed being  the  clays.  There  are  only  two,  however,  thus  far  of 
consequence  commercially,  in  the  ])roduction  of  the  metal:  bauxite  (to 
which  may  be  added  the  related  hydrated  oxides,  hydrargillite  and 
diaspore)  and  cryolite.  Cryolite  is  found  in  commercial  quantities 
only  in  south  Greenland,  and  was  formerly  the  only  ore  of  aluminum 
used,  being  still  employed  as  a  flux  in  the  extraction  of  the  metal. 
Bauxite  has  been,  for  some  years,  the  most  important  source  of  alumi- 
num and  its  salts.  Its  color  varias  from  gray  to  red,  according  to  the 
amount  of  iron  present,  the  composition  ranging  usually  between  the 


following  limits :  A1„0., 


30% 


-60%  ;  Fe.Os,  3%-25%  ;  SiO,,  0.5%-20%; 


TiO.,  0.0%-10%.  Besides  its  reduction  to  the  metal  bauxite  is  also 
utilized  in  the  manufacture  of  aluminum  salts,  refractory  bricks,  alun- 
dum  (fused  alumina)  for  use  as  an  abrasive,  and  in  the  refining  of  oil. 
The  most  important  producing  countries,  both  of  bauxite  and  the  metal, 
are  the  United  States  and  France,  the  former  yielding  more  than  60 
per  cent  of  the  world's  output.    In  1913  France  led.

Production  of  antimony  in  California  has  been  irregular,  and  sma 
in  amount  except  during  1915-17  when  the  high  war-time  prices  per- 
mitted American  producers,  for  a  short  period,  to  compete  with  Chinese

antimony.  Tlie  principal  commercial  production  of  antimony  in  Cali- 
fornia has  come  from  Kern,  Inyo  and  San  Benito  counties,  and  other 
occurrences  have  been  noted  in  Nevada,  Riverside  and  Santa  Clara 
counties.  The  commonest  occurrence  is  in  the  form  of  the  sulphide, 
stibnite ;  but  in  the  Kernville  and  Havilah  districts  in  Kern  County 
there  were  notable  deposits  of  the  native  metal,  beino:  among-  the  few 
localities  of  the  world  where  native  antimony  has  been  found.  There 
was  a  small  production  reported  from  San  Benito  County  and  develop- 
ment work  on  properties  both  in  Kern  and  San  Benito  counties. 

California   producers   claim   that   they   can   not   operate    profitably 

lunless  the  ])riee  of  antimony  be  above  12  cents  per  pound.    During  most 

[of  1925  and  1926  the  price  was  up,  at  times  as  high  as  23^,  and  as  a  con- 
sequence there  was  some  revival  of  antimony  mining  in   California. 

|Present   New   York   quotations    (August,    1928)    are   around   10^   per 
)ound  for   Chinese  brands.     China  is  the  principal  world  source   of 

[antimony. 

The  antimony  market  (New  York  being  the  chief  center)  is  recog- 
lized  as  one  of  the  most  unstable  of  the  metal  markets.    As  the  world's 

[requirements  for  antimony  are  comparatively  small,  the  prices  react 
sharply  if  an  extra  quantity  of  the  metal  be  thrown  onto  the  market, 
md  the  trade  becomes  so  cautious  that  the  market  may  disappear  alto- 

'gether,  causing  production  to  fall  off  rapidly. 

Pure  antimony  metal  and  manufactured  antimony  compounds  are  of 
considerable  importance  as  pigments  in  the  ceramic  industry.  The 
most  important  use  of  the  metal,  commercially,  is  in  various  alloys, 
particularly  tjqDC-metal  (with  tin  and  lead),  babbitt  (with  tin  and 
copper),  and  britannia  metal  (with  tin  and  copper).  An  alloy  of  6% 
antimony  and  9.4%  lead  is  being  extensively  used  in  making  battery 
^  plates  for  storage  batteries  for  automobiles,  airplanes,  and  radio 
apparatus.

dite  (FeAs04+2H20),  an  oxidation  product  of  arsenopyrite.  The 
occurrence  of  realgar  (AsS)  has  also  been  noted.  The  principal  source 
of  the  arsenic  of  commerce  in  the  United  States  has  been  as  a  by-product 
from  the  metallurgical  treatment  of  copper,  gold,  and  lead  ores.  It  is 
usually  recovered  in  the  form  of  the  tri-oxide,  or  'white  arsenic,'  for 
which  there  is  a  demand  for  the  preparation  of  insecticides,  for  use  in 
agriculture  and  horticulture,  and  especially  against  the  cotton-boll 
weevil  in  the  southern  states. 

Except  for  a  small  output  in  1924,  there  has  been  no  commercial 
recovery  of  arsenic  from  Californian  ores.  There  having  been  only  a 
single  operator,  the  figures  are  concealed  under  the  'Unapportioned' 
item. 

BERYLLIUM 

Bibliography:  Eng.  &  Min.  Jour.-Press,  Vol.  118,  No.  8,  p.  285, 
Aug.  23,  1924. 

Beryllium  is  a  metal  resembling  aluminum  closely  in  its  chemical 
character,  and  has  a  specific  gravity  of  1.85.  Several  alloys  have  been 
prepared  experimentally,  of  which  copper-beryllium  has  received  the 
most  attention.  The  addition  of  5%  beryllium  produces  a  golden-yellow 
alloy.  The  compounds  of  beryllium  at  present  used  commercially  are 
the  nitrate  and  oxide.  The  nitrate  is  used  by  incandescent  mantle 
manufacturers  to  harden  the  thorium  oxide  skeleton,  and  the  oxide  has 
been  added  to  materials  being  used  for  the  manufacture  of  abrasive 
compounds  and  in  dental  cements.  Beryllium  sulphate  has  been  used 
to  some  extent  in  medical  research. 

There  are  a  number  of  beryllium  minerals,  but  none  have  been  found 
in  commercial  quantities,  except  beryl,  which  is  a  beryllium-aluminum 
silicate.    The  chief  u.se  at  present  for  ground  beryl  is  as  an  addition  to 
porcelain    products,    where    it    reduces    the    coefficient    of    expansion 
Beryllium  metal  is  difficult  to  separate  from  aluminum. 

Beryl  occurs  in  California  in  the  pegmatite  dikes  of  the  tourmaline 
gem  district  in  northern  San  Diego  and  southwestern  Riverside  coun- 
ties. Thus  far  there  have  been  no  commercial  shipments  of  beryl  except 
for  gem  purposes  (the  pink  and  aquamarine  varieties). 

BISMUTH  ^ 

Bihliography:  Bulletins  38,  67,  91.    Am.  Jour.  Sci.,  1903,  Vol.  16. 

Several  bismuth  minerals  have  been  found  in  California,  notably 
native  bismuth  and  bismite  (the  ochre)  in  the  tourmaline  gem  district 
in  San  Diego  and  Riverside  counties,  near  Pala.  Other  occurrences  of  ' 
bismuth  minerals,  including  the  sulphide,  bismuthinite,  have  been  noted 
in  Inyo,  Fresno,  Nevada,  Tuolumne,  San  Bernardino,  and  Mono  coun- 
ties, but  only  in  small  quantities.  The  only  commercial  production 
recorded  was  20  tons  valued  at  $2,400,  in  1904,  and  credited  to  River- 
side County.  Recovery  of  bismuth  from  blister  copper  in  the  electro- 
lytic refinery  has  been  noted.  In  the  United  States,  the  principal 
recovery  of  bismuth  is  obtained  as  a  by-product  from  the  refining  of 
lead  bullion. 

The  uses  of  bismuth  are  somewhat  restricted,  being  employed  princi- 
pally in  the  preparation  of  medicinal  salts,  and  in  low  melting-point 


I  STATISTICS   OF    ANNUAL   PRODUCTION  43 

or  cliche  alloys.     These  alloys  are  utilized  in  automatic  fire  sprinkler 
systems,  in  electrical  fuses,  and  in  solders. 

Present  quotations  for  bismuth  are  around  $1.85  per  pound  for  the 
refined  metal. 

CADMIUM 

BiUiography:  U.  S.  Geol.  Surv.,  Min.  Res.  of  U.  S.,  1908,  1918. 

During  1917  and  1918,  cadmium  metal  was  recovered  by  the  electro- 
lytic zinc  plant  of  the  Llammotli  Copper  Company  in  Shasta  County. 
It  was  shipped  in  the  form  of  'sticks'  and  amounted  to  a  total  of  several 
thousand  pounds  for  the  two  years,  the  exact  figures  being  concealed 
under  'Unapportioned.'  That  was  the  first,  and  thus  far  the  only, 
commercial  production  of  cadmium  recorded  from  Californian  ore.  Cad- 
mium occurs  there  associated  with  zinc  sulphide,  sphalerite.  Cadmium 
also  occurs  in  the  Cerro  Gordo  Mine,  Inyo  County,  associated  with 

I    smithsonite  (zinc  carbonate). 

1  There  are  several  cadmium  minerals,  but  none  of  them  occur  in 
sufficient  quantities  individually  to  be  profitable  as  distinct  ores.  The 
cadmium  of  commerce  is  derived  as  a  by-product  in  the  reduction  of 
zinc  minerals  and  ores,  in  nearly  all  of  which  it  occurs  in  at  least  minute 
proportions,  the  average  ratio  being  about  1  of  cadmium  to  200  of  zinc. 
As  cadmium  behaves  m'etallurgically  much  the  same  as  zinc,  it  con- 
stitutes a  fraction  of  1  per  cent  of  nearly  all  metallic  zinc. 

Cadmium  is  produced  in  the  United  States  in  two  forms — metallic 
cadmium  and  the  pigment,  cadmium  sulphide.  The  principal  use  of 
the  metal  is  in  low-melting  point,  or  cliche  alloys,  and  its  salts  are 
utilized  in  the  arts,  medicine,  and  in  electroplating.  The  sulphide  is 
employed  as  a  paint  pigment,  being  a  strong  yellow,  which  is  unaffected 
by  hydrogen  sulphide  gas  from  coal  smoke.  It  is  also  employed  in 
coloring  glass  and  porcelain.  Cadmium  cliche  metal  is  stated  to  be 
superior  to  the  corresponding  bismuth  alloy,  for  making  stereotype 
plates.  Cadmium  is  also  used  in  bronze  telegraph  and  telephone  wires, 
and  gives  some  promise  of  being  utilized  in  electroplating. 

Present  quotations  for  cadmium  are  80^  per  pound  for  the  refined 
metal. 

COBALT 

Bihliographif:  Report  XIV.     Bulletins  67,  91.    U.  S.  G.  S.,  Min. 
Res.  of  U.  S.,  1912,  1918 

Occurrences  of  some  of  the  cobalt  minerals  have  been  noted  in  several 
[localities  in  California,  but  to  date  no  commercial  production  has 
resulted.  Some  of  the  copper  ores  of  the  foothill  copper  belt  in  Mari- 
posa and  Madera  counties  have  been  found  to  contain  cobalt  up  to  3%. 
The  most  notable  occurrence  thus  far  found  in  this  state  is  in  the 
Mar-John  Mine  near  Sheep  Ranch,  Calaveras  County.  Lenses  of 
smaltite  (CoAso),  have  been  uncovered  in  the  vein,  there,  and  several 
tons  taken  out  in  the  course  of  development  work ;  but  as  yet  there  have 
been  no  commercial  shipments. 

The  most  important  use  of  cobalt  is  in  the  manufacture  of  the  alloy, 
stellite,  in  which  it  is  combined  with  chromium,  for  making  high-speed 
lathe  tools,  and  non-tarnishing  cutlery  and  surgeons'  appliances.  The 
metal  is  also  used  in  electroplating,  similarly  to  nickel ;  and  the  oxide, 


44  MINERAL    INDUSTRY    OF    CALIFORNIA 

carbonate,  chloride,  sulphate  and  other  salts  are  used  in  ceramics  for 
coloring.  Some  of  the  organic  salts  of  cobalt  (acetate,  resinate,  oleate) 
are  employed  as  'driers'  in  paint  and  varnish. 

The  nominal  quotation  for  cobalt  is  around  $2.10  per  pound  for  the 
refined  metal. 

COPPER

Copper  is  second  only  to  gold  among  the  metals  mined  in  California. 
The  output  for  1927  "amounted  to  a  total  of  27,350,316  pounds  of 
recoverable  metal  valued  at  $3,582,888,  a  decrease  from  the  1926  figures] 
of  33,521,544  pounds  and  $4,693,014.    The  average  price  of  copper  for] 
1927  was  13.1<f  per  pound  against  14.0^  in  1926. 

A.S  for  several  years  past,  Plumas  County  ranks  first  for  1927,  with!

Copper  Production  of  the   United   States. 

According  to  preliminary  data  issued  by  the  U.  S.  Bureau  of  Mines,^ 
the  smelter  production  of  primary  copper  from  domestic  sourcas  during 
1927  amounted  to  1,684,040,983  pounds,  an  increase  of  approximately 
3%.  The  value  of  smelter  production  increased  approximately  9% 
in  1926.  The  average  price  of  2,836,000,000  pounds  of  copper  deliv- 
ered during  the  year,  as  reported  to  the  Bureau  of  Mines  by  selling 
agencies,  was  13. 1(^  per  pound.

Copper  Production  of  California  by  Years. 

Although  some  mining  of  copper  ores  in  a  small  way  had  been  done 
earlier,  shipments  in  appreciable  quantities  began  in  1861  and  con-

tinued  of  importance  up  to  the  end  of  1867,  when  a  total  of  68,631  tons 
(of  2376  pounds)  of  high-grade  ores,  and  847  tons  of  matte  or  'regulus'^ 
had  been  shipped  to  smelters  at  New  York,  Boston,  and  Swansea,  Wales. 
The  most  important  district  at  that  time  was  Copperopolis  and  vicinity 
in  Calaveras  County,  with  some  shipments  also  made  from  Mariposa,  El 
Dorado,  Fresno,  and  San  Luis  Obispo  counties.  From  1868  to  1882, 
the  output  was  insignificant.  There  are  wide  discrepancies  in  the  figures 
currently  recorded  for  copper  production  previous  to  1882  in  which 
year  the  data  of  the  U.  S.  Geological  Survey  began.  The  detailed  statis- 
tics of  the  California  State  Mining  Bureau  began  in  the  year  1894.

Bibliographij:  State  Mineralogist  Eeports  I  to  XXIII  (inc.), 
(except  III  and  VIII).  Bulletins  36,  45,  57,  91,  92,  95.  U.S. 
Geol.  Surv.,  Prof.  Paper  73. 

Gold  was  the  first,  and,  for  many  years,  the  most  important  single 
mineral  product  of  California.  Although  now  surpassed  for  a  number 
of  years  in  annual  value  hy  petroleum,  and  by  cement  beginning  with 
1920,  it  still  heads  our  metal  list,  and  California  continues  to  outrank 
all  the  other  gold-producing  states  of  the  United  States,  including 
Alaska.  In  fact,  at  present,  California  is  producing  approximately 
26%  of  the  gold  mined  in  the  entire  United  States. 

While  there  is  some  renewal  of  activity  in  the  development  of  gold 
placer  properties,  it  has  not  yet  become  reflected  in  an  increased  yield 
of  the  metal.  In  fact,  the  1927  figures  show  a  decrease  from  the  1926 
values. 

The  gold  yield  has  decreased  in  recent  years,  not  only  in  California 
but  in  the  country  as  a  whole.  Meanwhile,  the  actual  gold  reserves 
(monetary  stock  on  hand)  of  the  United  States  has  increased  to  such  an 
extent  that  we  now  hold  practically  one-half  of  the  world's  stock.

STATISTICS   OF   ANNUAL   PRODUCTION 


47 


The  production  of  gold  in  California  in  1927  totaled  564,585.50 
fine  ounces,  worth  $11,671,018,  being  a  decrease  of  12,212.90  fine 
ounces  from  the  1926  yield.  The  '  deep '  or  lode  mines  output  accounted 
for  $5,833,705,  and  the  placers  (mainly  the  dredges)  produced  $5,837,- 
313.  As  the  Division  of  Mines  and  Mining  has  never  independently 
gathered  the  statistics  of  the  gold  and  silver  production,  these  figures,  as 
in  former  years,  are  published  b}"  cooperation  with  and  through  the 
courtesy  of  Mr.  J.  M.  Hill  of  the  Division  of  Minerals  and  Statistics,

The  largest  gold  production  for  1927  is  reported  from  Yuba  County 
with  an  output  of  167,774.20  fine  ounces  ($3,468,201)  ;  Nevada  County 
with  102,903.07  fine  ounces  ($2,127,195)  second;  Amador  County 
with  93,011.27  fine  ounces  ($1,922,714)  third;  Sacramento  County  with 
58,595.57  fine  ounces,  fourth;  followed  by  Sierra  and  Trinity  counties 
in  fifth  and  sixth  places,  respectively.  It  will  be  noted  as  in  1926  Yuba 
County  was  the  largest  gold  producer,  with  Nevada,  Amador,  and 
Sacramento  following  respectively  in  the  same  order.  The  Yuba  and 
Sacramento  production  came  almost  entirely  from  dredges,  while  that 
from  Nevada  and  Amador  came  mainly  as  lode  gold. 

The  following  is  quoted  from  the  advance  chapter  on  Gold  in  1927, 
by  courtesy  of  Mr.  J.  ]\I.  Hill  of  the  U.  S.  Bureau  of  Mines : 

"The  value  of  the  mine  production  of  gold  in  California  in  1927  decrea.sed  $252,463, 
or  2  per  cent,  as  compared  with  1926.  Lode  mines  yielded  50  per  cent  and  placer 
mines  50  per  cent  of  the  total  gold  in  1927,  as  compared  with  56  per  cent  and  44 
per  cent  in  1926,  61  per  cent  and  39  per  cent  in  1925,  and  65  per  cent  and  35  per 
cent,  respectively,  in  1924. 

"Four  counties  produced  more  than  $1,000,000  each  in  gold  in  1927  as  compared 
with  four  counties  in  1926  ;  Sierra  County  mines  did  not  reach  the  million  mark  in 
gold  value  in  either  1927  or  1926.  Yuba,  with  $3,468,201,  produced  largely  by 
dredges,  was  first  in  rank;  Nevada,  with  $2,127,195,  largely  from  gold  lode  mines, 
was  second;  Amador,  with  $1,922,714.  almost  entirely  from  gold  lode  mines,  was 
third;  and  Sacramento,  with  $1,211,278,  entirely  from  placers,  mostly  worked  by 
dredges,  was  fourth.  The  fifth  largest  output  of  gold,  $678,873,  came  from  Sierra 
County,  largely  from  gold  lode  mines,  and  was  followed  by  Trinity  County  with 
$409,492,  largely  from  dredge  and  hydraulic  placer  mines.  Calaveras  County, 
which  was  fifth  in  rank  in  1926,  dropped  to  eighth  place  in  1927,  being  preceded  by 
Plumas  County  in  its  value  of  gold. 

"The  yield  of  gold  from  465  placer  mines  in  1927  was  valued  at  $5,837,313,  an 
increase  of  12  per  cent  as  compared  with  the  placer  output  from  483  mines  in  1926. 
There  was  an  increased  gold  yield  of  10  per  cent  by  dredges,  28  per  cent  by  drift 
mines,  75  per  cent  by  hydraulic,  and  16  per  cent  by  surface  mines,  respectively,  as 
compared  with  1926.  In  1927  dredges  yielded  9  4  per  cent,  drift  mines  2  per  cent, 
hydraulic  mines  2  per  cent,  and  surface  workings  2  per  cent  of  the  gold  from 
California  placer  deposits.  Production  of  gold  by  25  dredges  operating  in  1927  was 
$5,461,929,  as  compared  with  $4,950,545,  by  23  dredges  in  1926  and  $4,750,842  by 
24  dredges  in  1925. 

"The  output  of  gold  from  318  lode  mines  in  California  in  1927  was  valued  at 
$5,833,705,  a  decrease  of  13  per  cent  as  compared  with  1926,  following  declines  of 
16  per  cent  in  1926  from  1925  and  7  per  cent  in  1925  from  1924. 


48  MINERAL    INDUSTRY    OP    CALIFORNIA 

"Gold  ore  and  tailings  treated  in  1927  yielded  93  per  cent,  copper  ore  and  tailings 
yielded  6  per  cent,  and  silver  ore  and  tailings  yielded  1  per  cent  of  the  total  gold 
from  lode  mines.  Amalgamation  mills  in  1927  recovered  approximately  75  per 
cent,  cyanidation  plants  15  per  cent,  and  smelters  10  per  cent  of  the  gold  lode 
output  of  California,  as  compared  with  75  per  cent,  17  per  cent,  and  8  per  cent, 
respectively,   in   1926. 

"It  is  estimated  that  approximately  4  per  cent  of  the  gold  output  from  lode  jnines 
was  stolen  and  sold  by  'high  graders'  in  1927,  a  reduction  of  2  per  cent  over  each 
of  the  two  preceding  years. 

"In  1927  there  were  33  companies  in  the  state  that  produced  more  than  1000 
ounces  of  gold  each,  and  they  contributed  91  per  cent  of  the  total  gold  output  of 
the  state.  This  is  a  decrease  of  1  per  cent  from  the  34  companies  that  produced 
more  than  1000  ounces  each  in  1926.  Of  the  33  larger  companies  7  produced  more 
than  20,000  ounces  each  and  2  more  than  50,000  ounces;  1 1  of  them  operated  22 
gold  dredges,  2  drift  placer  mines,  1  a  silver  mine,  3  operated  copper  mines,  and  10 
operated  gold  lode  mines.  The  10  largest  gold-producing  companies  in  California  in 
1927,  in  order  of  output,  were  the  Yuba  Consolidated  Gold  Fields  (6  dredges), 
Natomas  Company  of  California  (6  dredges).  Empire  Mines  Company  (gold  lode), 
Kennedy  Mining  and  Milling  Company  (gold  lode),  North  Star  Mines  Company  (gold 
lode),  Original  Sixteen  to  One  Mine  (Inc.)  (gold  lode),  Argonaut  Mining  Company 
(gold  lode),  Central  Eureka  Mining  Company  (gold  lode),  Walker  Mining  Company 
(copper   mine),   and   the   Original    Mining   and    Milling   Company    (gold    lode)." 

Total  Gold  Production  of  California. 

The  presence  of  gold  in  stream  gravels  near  Los  Angeles  was  known 
and  worked  in  a  small  way  by  the  Indians,  at  least  as  early  as  1841/ 
and  possibly  1820.-  On  March  2,  1844,  Don  Manuel  Castanares,  deputy 
for  California  to  the  Congress  of  Mexico,  reported^  to  his  government 
that  placers  near  Los  Angeles  had  produced  up  to  December,  1843,  a 
total  of  2000  ounces  of  gold  dust,  most  of  which  had  been  sent  to  the 
United  States  mint  at  Philadelphia. 

As  the  padres  and  the  rancheros  discouraged  the  quest  of  gold  this 
early,  small  production  caused  no  particular  excitement.  It  was  not 
until  James  W.  Marshall's  finding  of  gold  nuggets  in  the  tail-race  of 
Sutter's  saw  mill  on  the  American  River,  January  24, 1848,  was  heralded 
abroad  that  the  great  ru.sli  began,  and  California  became  a  common- 
wealth of  first  rank  almost  over  night.  There  are,  however,  no  authentic 
'data  on  gold  production  prior  to  1848,  other  than  occasional,  scattered 
references  such  as  above  quoted. 

The  following  table  was  originallj'  compiled  by  Chas.  G.  Yale,  of  the 
Division  of  Mineral  Resources,  U.  S.  Geological  Survey,  but  for  a  num- 
ber of  years  statistician  of  the  California  State  Mining  Bureau  and  the 
U.  S.  Mint  at  San  Francisco.  The  authorities  chosen  for  certain  periods 
were :  J.  D.  Whitney,  state  geologist  of  California ;  John  Arthur 
Phillips,  author  of  "Mining  and  Metallurgy  of  Gold  and  Silver" 
(1867);  U.  S.  Mining  Commissioner  R.  W.  Raymond;  U.  S.  Mining 
Commissioner  J.  Ross  Browne ;  Wm.  P.  Blake,  Commissioner  from  Cali- 
fornia to  the  Paris  Exposition,  where  he  made  a  report  on  "Precious 
Metals"  (1867)  ;  John  J.  Valentine,  author  for  many  years  of  the 
annual  report  on  precious  metals  published  by  Wells,  Fargo  &  Com- 
pany's Express;  and  Louis  A.  Garnett,  in  the  early  days  manager  of 
the  San  Francisco  refinery,  where  records  of  gold  receipts  and  ship- 
ments were  kept.  Mr.  Yale  obtained  other  data  from  the  reports  of 
the  director  of  the  Q.  S.  Mint  and  the  director  of  the  U.  S.  Geological 
Survey.  The  authorities  referred  to,  who  were  alive  at  the  time  of  the 
original  compilation  of  this  table  in  1894,  were  all  consulted  in  person 
or  by  letter  by  Mr,  Yale  with  reference  to  the  correctness  of  their 
published  data,  and  the  final  table  quoted  was  then  made  up.

A  small  tonnage  of  iron  ore  (magnetite)  was  produced  in  California 
tluring  tlie  year  1927,  from  beach  sand,  and  utilized  for  foundry  flux 
and  in  steel  refining  at  open-hearth  plants.  As  there  was  only  a  single 
operator,  the  figures  are  concealed  under  the  'unapportioned'  total. 
There  is  also  some  tonnage  utilized  in  the  manufacture  of  paint  pig- 
ment, and  which  is  credited  to  'mineral  paint'  in  these  statistical 
^reports. 

There  are  considerable  deposits  of  iron  ore  known  in  California, 
laotably  in  Shasta,  Madera,  Placer,  Riverside,  San  Bernardino  and  Los 
A.ngeles  counties,  but  production  has  so  far  been  limited  for  lack  of 
jin  economic  supply  of  coking  coal.  Some  pig-iron  has  been  made, 
itilizing  charcoal  for  fuel,  both  in  blast  furnaces  and  by  electrical 
'eduction ;  also,  f errochrome,  ferromanganese,  and  f errosilicon  have 
')een  made  in  California.

tion at  Hotaling  in  Placer  County.  Charcoal  was  used  in  lieu  of  coke.  Though  producing  a  superior  grade  of  metal, 
they  were  obliged  finally  to  close  down,  as  they  could  not  compete  with  the  cheaper  English  and  eastern  United  States

Small  amounts  of  manganase  ore  from  California  have  been  shipped 
in  past  years  to  steel  plants  along  the  Pacific  Coast.  These  ores  showed 
analyses  of  from  45%  to  55%  Mn  and  were  utilized  by  plants  for 
ferromanganese. 

Importations  of  foreign  manganese  ores  to  the  United  States  in  1927, 
mainly  from  Brazil,  amounted  to  a  total  of  622,067  long  tons  valued 
at  8,487,016,  compared  with  368,341  tons  and  $11,075,771  in  1926. 
The  Tariff  Act  of  1922  provides  for  an  import  duty  of  1^  per  pound 
on  the  metallic  manganese  contained,  for  "manganese  ore  or  concen-

trates  containing  in  excess  of  30  per  centum  of  metallic  manganese." 
The  bulk  of  such  ore  is  consumed  in  the  large  steel-producing  centers 
of  the  eastern  United  States. 

Much  valuable  research  work  has  been  done  in  recent  years,  particu- 
larly by  companies  operating  in  Montana  and  Virginia,  in  the  benefi- 
ciation  of  manganese  ores.  The  success  of  their  processes  appears 
assured.  In  reply  to  the  recent  suggestion  of  certain  steel  interests  to 
have  the  manganese  import  duty  removed,  the  manganese  operators 
have  organized  the  American  Manganese  Producers'  Association,  which 
will  work  for  retention  of  the  tariff.  Such  retention  will  enable  the 
domestic  industry  to  grow  and  to  further  develop  ore-dressing  methods 
that  will  make  available  large  tonnages  of  low-grade  material  not  now 
marketable. 

Manganese  Ore  Production  in  California,  by  Years. 

Production  of  manganese  ore  in  California  began  at  the  Ladd  Mine, 
San  Joaquin  County,  in  the  Tesla  District  in  1867.  When  shipments 
of  this  ore  to  England  ceased  late  in  1874,  upwards  of  5000  tons  had 
been  produced  by  that  property.  For  some  j^ears  following  that,  the 
output  was  small.  The  tabulation  herewith  shows  California's  output 
of  manganese  ore,  annually,  since  1887,  when  the  compilation  of  such 
figures  was  begun  by  the  State  Mining  Bureau :

MOLYBDENUM 

Bibliography:  State  Mineralogist  Reports  XIV,  XVII.  Bulletins

Molybdenum  is  used  as  an  alloy  constituent  in  the  steel  industry, 
and  in  certain  forms  of  electrical  apparatus.  Included  in  the  latter 
is  its  successful  substitution  for  platinum  and  platinum-iridium  in 
electric  contact-making  and  -breaking  devices.  In  alloys  it  is  used 
similarly  to  and  in  conjunction  with  chromium,  cobalt,  iron,  manganese, 
nickel,  tungsten,  and  vanadium.  The  oxides  and  the  ammonium  salt 
have  important  chemical  uses. 


STATISTICS   OF   ANNUAL   PRODUCTION  53 

The  two  principal  molybdenum  minerals  are :  the  sulphide,  molyb- 
denite ;  and  wnlf enite,  lead  molybdate ;  the  former  furnishing  prac- 
tically the  entire  commercial  output.  Molybdenite  is  found  in  or  asso- 
ciated with  acidic  igneous  rocks,  such  as  granite  and  pegmatite.  The 
chief  commercial  sources  have  been  New  South  Wales,  Queensland  and 
Norway,  with  some  also  from  Canada ;  but  the  United  States  is  now  able 
to  supply  its  own  requirements. 

The  growing  consumption  of  molybdenum  by  alloy-steel  makers  in 
the  United  States  has  been  stimulated  by  the  fact  that  molybdenum 
alone  of  the  steel-alloying  metals  can  be  produced  commercially  in  the 
United  States  to  an  extent  which  avoids  all  necessity  for  importation. 
Another  fact  has  been  the  marked  adaptability  of  molybdenum  steels 
to  large-scale  production  of  automobile  and  other  parts. 

The  most  important  development  of  1924—1925  was  the  elimination 
of  ferromolybdenum  from  the  market  due  to  the  substitution  of  calcium 
molybdate  as  the  furnace  addition  by  the  entire  alloy-steel  industry. 
Calcium  molj^bdate  is  stated  to  be  not  only  easier  and  less  costly  to 
prepare,  but  it  introduces  the  molybdenum  into  the  steel  bath  in  a 
much  purer  form,  the  resulting  steel  being  superior  to  that  made  with 
ferromolybdenum. 

Deposits  of  disseminated  molybdenite  are  known  in  several  localities 
in  California,  and  in  at  least  two  places  it  occurs  in  small  masses 
associated  with  copper  sulphides.  The  only  recorded  commercial  ship- 
ments of  molybdenum  ore  in  California  were  during  the  war,  1916- 
1918.  Some  development  work  has  been  recently  done  on  a  high-grade 
deposit  at  the  head  of  the  Kaweah  River,  Tulare  County.

ment work,  but  not  treated  nor  disposed  of,  as  thej^  were  unable  to  get

In  California  the  platinum  group  metals  are  obtained  as  a  by-product 
from  placer  operations  for  gold.  The  major  portion  of  it  comes  from 
the  dredges  working  in  Butte,  Sacramento,  Stanislaus  and  Shasta 
countiCvS,  with  a  small  amount  coming  from  the  hydraulic  and  surface- 
sluicing  mines  of  Del  Norte,  Humboldt,  Siskiyou,  and  Trinity  counties. 

Tlie  production  of  platinum  metals  in  California  for  1927  totaled 
183  ounces  crude,  containing  139  fine  ounces  valued  at  $10,757,  com- 
pared with  tlio  1926  figures  of  322  fine  ounces  and  $32,005.  Of  this 
amount  102  fine  ounces  or  73%  came  from  the  gold  dredges. 

In  addition  to  the  above  metal  there  was  some  platinum  mined 
but  not  sold  in  1927  in  Butte,  Trinity  and  Yuba  counties. 

Of  the  al)ove  183  fine  ounces  at  least  37  fine  ounces  were  iridium, 
osmium,  palladium  and  ruthenium.  Most  of  the  platinum  refiners 
pay  for  the  osmiridium  on  the  basis  of  its  iridium  content.  Crude 
'platinum'  is  really  a  mixture  of  the  metals  of  that  group,  and  car- 
ries varying  percentages  of  platinum,  iridium,  osmiridium  or  iridos- 
mine,  with  occasionally  some  ruthenium  and  palladium.  In  addition 
to  the  above-noted  production,  there  is  usually  some  platinum  recov- 
ered as  a  by-product  in  the  gold  refinery  of  the  mint,  but  which  can 
not  be  assigned  to  the  territory  of  its  origin  for  lack  of  knowing  to 
which  lots  of  gold  it  belongs.  Some  platinum  and  palladium  are  also 
recovered  in  the  electrolytic  refining  of  blister  copper. 

For  1926,  the  distribution  by  counties  of  California's  platinum  yield 
was  as  follows :

Uses,    Markets,   and    Consumption. 

Besides  its  well-known  uses  in  jewelry,  dentistry  and  for  chemical- 
Avare,  an  important  industrial  development  of  recent  years  employs 
platinum  as  a  catalyzer  in  the  'contact  process'  of  manufacturing  con- 
centrated sulphuric  acid.  It  is  also  necessary  for  certain  delicate  parts 
of  the  ignition  systems  in  automobiles,  motor  boats  and  aeroplanes. 
Experiments  have  been  made  to  find  alloys  which  can  replace  platinum 
for  dishes  and  crucibles  in  analytical  work,  but  so  far  with  only  slight  || 
success. 

According  to  Hill,'  the  total  consumption  of  platinum  metals  in

Prices. 

The  prices  of  all  the  metals  of  the  platinum  group  fluctuated  con- 
siderably during  1927,  dropping  in  June,  when  they  reached  their  low 
point.  The  price  of  pure  platinum  per  fine  ounce  was  $105  in  Janu- 
ary, 1927,  dropping  to  $62  in  June  and  ending  the  year  at  $72, 
Palladium  ended  the  year  at  $49  to  $50,  iridium  at  $175  to  $185.  In 
April  there  was  a  rumor  that  Russian  platinum  would  be  sold  through 
Amtorg  Company,  which  sent  the  market  price  down.  There  were 
also  large  shipments  from  Colombia.

The  production  of  quicksilver  for  1927  in  California  was  6488  flasks 
('of  75  pounds,  avoirdupois)  valued  at  $714,418.  This  was  an  increase 
in  both  quantity  and  value  over  the  1926  figure  of  5892  flasks  valued 
at  $516,382.  This  production  came  from  Lake,  Monterey,  Napa, 
Orange,  San  Benito,  San  Luis  Obispo  and  Sonoma  counties,  the  largest 
production  coming  from  San  Benito,  with  Napa  in  second  place.  The 
average   price    received    during    1927,    according    to    the    producers'

reports  to  the  Division  of  Mines  and  Mining,  was  $111.67  per  flask,  as 
against  $89.64  in  1926,  and  the  record  average  of  $114.03  for  the  year 
1918. 

During  1927  there  were  sharp  fluctuations  of  quotations  on  quick- 
silver. The  year  started  at  $100.33,  going  to  $123.33  in  April,  and 
ending  the  year  at  $129.50.  In  June  the  price  quoted  changed  from 
a  75-pound  flask  to  a  76-pound  flask. 

The  average  quotations  for  quicksilver  in  1927  were  $117.25  for  a 
76-pound  flask  at  San  Francisco,  or  $115.71  (for  75  pounds),  against 
$87.64  (75  pounds)  in  1926.  The  average  quotations  for  1927  in  New 
York  were  $118.16  for  a  76-pound  flask,  or  $116.60  for  a  75-pound 
flask.

STATISTICS   OF   ANNUAL   PRODUCTION 


57 


The  U.  S.  Bureau  of  Mines  reported  the  total  production  of  the 
United  States  for  1927  at  11,276  flasks  valued  at  $1,314,782  (using 
$116.60  as  the  average  of  New  York  quotations).  Outside  of  Cali- 
fornia, the  principal  yield  came  from  Texas  and  Washington,  with  a 
few  flasks  from  Nevada,  Alaska,  Arizona,  and  Idaho.  California  pro- 
duction was  approximately  53%  of  the  total. 

The  imported  quicksilver  ^  in  1927  amounted  to  24,650  flasks.  Of 
these,  13,663  flasks  came  from  Spain,  9089  flasks  from  Italy,  and  1843 
flasks  from  Mexico.  The  rise  in  price  in  the  last  quarter  of  1926  and 
1927  was  due  to  an  increased  demand  in  the  United  States,  as  shown 
by  the  increased  production  and  imports  and  the  continued  demand  of 
continental  Europe. 


Uses. 

The  most  important  uses  of  quicksilver  are  the  recovery  of  gold  and 
silver  by  amalgamation,  and  in  the  manufacture  of  fulminate  for  explo- 
sive caps,  of  drugs,  of  electric  appliances,  and  of  scientific  apparatus. 
By  far  the  greatest  consumption  is  in  the  manufacture  of  fulminate 
and  drugs.  Radio  tubes  and  electrical  appliances  are  taking  increasing 
amounts.

58  MINERAL    INDUSTRY    OF    CALIFORNIA 

Total  amount  and  value  of  the  quicksilver  production  of  California, 
as  given  in  available  records,  are  shown  in  the  preceding  tabulation. 
Though  the  New  Almaden  Mine  in  Santa  Clara  County  was  first  worked 
in  1824,  and  has  been  in  practically  continuous  operation  since  1846 
(the  yield  being  small  the  first  two  years),  there  are  no  available  data 
on  the  output  earlier  than  1850.  Previous  to  June,  1904,  a  'flask'  of 
quicksilver  contained  76i  pounds,  but  since  that  date  75  pounds.  In 
compiling  this  table  the  following  sources  of  information  were  used: 
for  1850-1883,  table  by  J.  B.  Randol,  in  Report  of  State  Mineralogist, 
IV,  p.  336 ;  1883-1893,  U.  S.  Geological  Survey  reports ;  1894  to  date, 
statistical  bulletins  of  the  State  Mining  Bureau;  also  State  Mining 
Bureau,  Bulletin  27,  "Quicksilver  Resources  of  California,"  1908,  p.  10  .

Bibliography:  State  Mineralogist  Reports  IV,  VIII,  XII-XXIII 
(inc.).    Bulletins  67,  91.    Min.  &  Sci.  Press,  March  1,  1919. 

Except  for  the  early-day  production  from  the  silver  mines  of  the 
Calico  district  and  the  more  recent  production  from  those  of  the 
Randsburg  area,  both  of  which  are  in  San  Bernardino  County,  the 
recovery  of  silver  in  California  has  been  largely  as  a  by-product  from 
its  association  with  copper,  lead,  zinc,  and  gold  ores. 

In  1927  silver  production  of  California  totaled  1,620,242  fine  ounces 
valued  at  $918,677,  compared  witli  2,022,460  ounces  values  at  $1,262,- 
015  in  1926.  Of  the  1927  yield  20,903  ounces  valued  at  $11,852  came 
from  placers.  The  average  price  of  domestic  silver  during  1927  was 
56.7^^  per  ounce  in  New  York  against  62. 4f  in  1926. 

The  figures  below  are  those  of  the  U.  S.  Bureau  of  Mines,  Depart-

The  following  paragraphs  are  quoted  from  the  U.  S.  Bureau  of 
Mines,  Department  of  Commerce,  Advance  Chapter  on  Gold  and  Silver 
for  1927,  by  courtesy  of  Mr.  J.  M.  Hill,  statistician  in  charge  of  the 
San  Francisco  branch  office : 

"The  mine  production  of  silver  in  California  in  1927  was  1,620,242  ounces,  valued 
at  $918,677,  a  decrease  of  20  per  cent  in  quantity  and  27  per  cent  in  value  as  com- 
pared with  192G.  Three  counties  yielded  more  than  100,000  ounces  of  silver  each  in 
1927,  namely,  San  Bernardino  County,  with  788,580  ounces  largely  from  silver  ore 
produced  by  the  California  Rand  Silver  (Inc.)  ;  Plumas  County,  with  315,887  ounces, 
largely  from  copper  ores  of  the  Engels  and  Walker  mines ;  Shasta  County,  with 
123,917  ounces,  largely  from  zinc  and  copper  ores.  Inyo  and  Mono  counties  were 
in  the  100,000  ounce  cla.ss  in  192G,  but  each  produced  less  than  100,000  ounces  in 
1927.  The  fourth  largest  producer  of  silver  was  Napa  County,  with  99,532  ounces 
from  silver  ores,  and  this  was  followed  by  Inyo  County,  with  83,570  ounces,  mostly 
from  lead  ores. 

"The  yield  of  silver  from  placer  mines  in  1927  was  20,903  ounces,  8  per  cent  more 
than  in  1926  and  over  1  per  cent  of  the  total  silver  output  of  the  state.  Of  the 
1,599,339  ounces  of  silver  produced  at  lode  mines  in  1927  silver  ore  and  tailings 
yielded  58  per  cent   (same  as  in  1926),   copper  ore  and  tailings  25  per  cent    (20  per

lead-zinc  ore  2  per  cent,  and  lead-copper  ore  less  than  one-fourth  of  1  per  cent. 

"Each  of  43  properties  in  1927  produced  more  than  1000  ounces  of  silver  as 
compared  with  46  properties  in  1926,  and  these  mines  yielded  98  per  cent  of  the 
total  silver  produced  in  the  state  in  both  1927  and  1926.  At  27  properties  the  yield 
was  between  1000  and  10,000  ounces  (31  in  1926),  at  13  between  10,000  and  100,000 
(10  in  1926),  at  2  between  100,000  and  300,000  (4  in  1936),  and  at  1  mine  in  excess 
of  700,000  ounces  in  1927.  No  mine  in  California  produced  as  much  as  1,000,000 
ounces  of  silver  in  1927.  The  10  largest  producers  of  silver  in  California  in  1927  in 
order  of  output  were  the  California  Rand  Silver  (Inc.),  Walker  Mining  Company, 
Engels  Copper  Mining  Company,  Palisades  Mines  Company,  California  Zinc  Company, 
Mason  Mining  Company  (Balaklala),  Mono  Mining  Company  of  Nevada,  American 
Metals  (Inc.)  (Darwin),  North  Star  Mines  Company,  and  the  Santa  Catalina  Island 
Company."

(for  1925),  the  values  sho^VIl  for  1880-1904  (inc.)  were  taken  from  the 
reports  of  the  Director  of  the  Mint,  of  which  the  figures  for  1880-1896 
(inc.)  were  based  on  'coinage  value'  ($1.2929  per  fine  ounce).  We 
have  recalculated  these  to  commercial  value,  using  the  price  table  of  the 
U.  S.  Geological  Survey  (McCaskey,  H.  D.,  Gold  and  Silver,  1913: 
Mineral  Resources  of  the  U.  S.,  Part  I,  p.  847).  From  1905  to  date,  the 
figures  are  those  of  the  U.  S.  Geological  Survey  and  its  successor,  the

TIN 

Bihliogmphy:  Reports  XV,  XVII,  XVIII.     Bulletins  67,  91. 

In  1927  tliere  was  no  production  of  tin,  although  there  is  consider- 
able work  being  done  to  reopen  the  Temescal  mine  in  Riverside  County 
near  Corona.  There  Avas  an  output  from  the  district  during  1891-1892 
as  tabulated  below.  Small  quantities  of  stream  tin  have  been  found  in 
some  of  the  placer  workings  in  northern  California,  but  never  in  paying 
amounts. 

Two  occurrences  have  also  been  noted,  in  northern  San  Diego  County. 
Crystals  of  cassiterite  were  found  there,  associated  with  blue  tourma- 
line crystals,  amblygonite  and  beryl.  No  commercial  quantity  has  been 
developed,  only  small  pockets  liave  been  taken  out. 

The  principal  sources  of  the  world's  supply  of  tin  are  the  islands  of 
Banka,  Billiton  and  Singkep,  Netherlands  India  (Dutch  East  Indies), 
followed  by  the  Federated  Malay  States  (Perak,  Pahang,  Negri  Sem- 
bilan  and  Selangor).  Bolivia,  Siam,  Cornwall,  Transvaal,  New  South 
Wales,  Queensland  and  Tasmania  are  also  important  sources.  A 
measureable  amount  of  the  metal  is  also  recovered  by  detinning  scrap 
and  old  cans.

TITANIUM 

BihliograpJuj :  State  Mineralogist's  Report  XXIII. 

In  1927  for  the  first  time  titanium  minerals  were  mined  in  Cali- 
fornia. These  operations  were  in  Los  Angeles  County,  where  one  of 
the  largest  deposits  of  titanium  ore  in  the  United  States  is  located. 
There  were  two  separate  operations,  one  worked  the  black  beach  sands, 
which  probably  contained  approximately  20%  titaniferous  iron  and 
magnetite,  the  gangue  being  silica  and  several  silicates.  The  other 
is  a  lode  deposit  in  the  San  Gabriel  Mountains. 

Titanium  is  widely  distributed  in  a  variety  of  minerals,  but  its 
commercial  sources  are  limited  to  three  forms,  rutile  (oxide),  ilmenite 
(titanite),  and  titaniferous  magnetite  (iron  ore  rich  in  titanium). 
There  are  several  known  areas  where  large  deposits  of  these  minerals 
are  found  in  America,  mostly  titaniferous  iron.  Of  the  titaniferous 
iron  deposits  only  a  portion  of  the  Adirondack  deposit,  some  small 
deposits  in  North  and  South  Carolina,  and  those  in  Los  Angeles  County 
are  capable  of  being  separated  into  a  high-grade  ilmenite  and  a  low 
titanium  magnetite. 

The  metal  is  used  in  several  different  alloys  with  iron,  copper  and 
aluminum  and  for  green  and  white  paint  pigments,  the  only  colors  of 
titanium  pigments  now  in  common  use.  It  is  also  used  in  dyes,  rubber, 
as  a  porcelain  glaze,  in  glass,  and  cement  made  from  high-titanium 
iron  slags.    This  cement  is  resistant  to  the  action  of  acids. 

The  market  price  of  titanium  minerals  varies  as  to  the  titanium  oxide 
it  contains.  Rutile  96%  TiO  (a)  lU  to  13^  a  pound,  ilmenite  52  to  60%; 
TiO  @  $10  to  $15  a  ton,  and  ilmenite  32  to  35 7o  TiO  @  $7  to  $8  a  ton, 
all  prices  Atlantic  seaboard. 

TUNGSTEN 

BiUiography:  Reports  XV,  XVII,  XVIII,  XXII.  Bulletins  38, 
67,  91,  95.  .  U.  S.  G.  S.  Bull.  652.  Proc.  Colo.  Sci.  Soc.  Vol.  XL 
South  Dakota  School  of  IMines,  Bulletin  No.  12.  Eng.  and  Min. 
Jour.-Press,  Vol.  113,  pp.  666-669,  Apr.  22,  1922. 

The  commercial  production  of  tungsten  ores  and  concentrates  in 
California  began  in  1905 ;  and  has  been  continuous  since,  with  the 
exception  of  1920-1922  (inclusive),  when  the  mines  were  shut  down 
owing  to  low  prices  due  to  excess  stocks  following  the  war  and  to  lack 
of  tariff  protection  against  foreign  importations.  Production  was 
resumed  on  a  small  scale  late  in  1923,  and  is  now  at  practically  its 
pre-war  average  annual  tonnage,  though  the  1927  figures  are  less  than 
those  for  1926. 

The  material  shipped  in  1927  included  both  high-grade  sorted  ore 
and  concentrates,  coming  from  a  property  in  San  Bernardino  County. 
Prices  during  1927  ranged  from  $10.25  to  $11.75  per  unit,  duty  paid, 
for  Chinese  wolframite,  with  domestic  scheelite  $10  to  $11.  Pres- 
ent prices  are  approximately  the  same. 

Tungsten  ore  has  been  produced  in  California  principally  in  the 
Atolia-Randsburg  district  in  San  Bernardino  and  Kern  counties,  fol- 
lowed by  the  Bishop  district  in  Inyo  County,  with  small  amounts 
coming  from  Nevada  County  and  from  the  district  near  Goffs,  in  eastern 
San  Bernardino.    Most  of  the  California  tungsten  ore  is  scheelite  (cal- 


62  MINERAL    INDUSTRY    OF    CALIFORNIA 

cium  tungstate),  though  wolframite  (iron-manganese  tungstate)  and 
hiibernite  (manganese  tungstate)  also  occur.  The  deposits  at  Atolia 
are  the  largest  and  most  productive  scheelite  deposits  known/  and  the 
output  has  in  some  years  equaled  or  exceeded  that  of  ferberite  (iron 
tungstate)  from  Boulder  County,  Colorado.  It  is  interesting  in  this 
connection  to  note  that,  in  practically  all  other  tungsten  producing 
districts  of  the  world,  wolframite  is  the  important  constituent. 

Imports  of  foreign  tungsten  ore  and  alloys  into  the  United  States 
during  1927  amounted  to  1,613,616  pounds  valued  at  $308,106,  com- 
pared with  3,441,975  pounds  valued  at  $871,294  in  1926,  and  10,362 
long  tons  of  ore  valued  at  $11,409,237  in  1918,  which  ores  were  duty 
free  up  to  September  22,  1922.  Owing  to  lack  of  protection  against  the 
cheap  coolie  labor  of  Asiatic  tungsten  mines,  and  low  market  prices, 
practically  all  of  the  tungsten  mines  in  the  United  States  were  closed 
down  from  the  middle  of  1919  to  the  latter  part  of  1923.  Quotations 
during  1922  ranged  around  $2.50  per  unit,  up  to  September.  The 
Tariff  Act  of  1922  placed  a  duty  on  tungsten  ore  or  concentrates  of  45^ 
per  pound  on  tlie  metallic  tungsten  contained  therein.  Duties  are  also 
X)rovided  for  imported  tungsten-bearing  alloys.  Most  of  the  imported 
ore  is  coming  from  Cliina,  with  smaller  amounts  from  Malaya  and 
Bolivia. 

Uses. 

The  metal,  tungsten,  is  used  mainly  in  the  steel  industry  and  in  the 
manufacture  of  electrical  appliances,  including  the  well-known  tung- 
sten filament  lamps.  Because  of  its  resistance  to  corrosion  by  acids,  it 
is  valuable  in  making  certain  forms  of  chemical  apparatus.  Its  employ- 
ment in  tool-steel  alloys  permits  the  operation  of  cutting  tools,  such  as 
in  lathe  work,  at  a  speed  and  temperature  at  which  carbon  steel  would 
lose  its  temper — hence  the  name  'high  speed'  steels  for  these  tungsten 
alloys.  As  made  in  the  United  States,  tungsten  forms  13%  to  20%  of 
such  steels.  Some  chromium,  nickel,  cobalt,  or  vanadium  are  sometimes 
also  included.  Tungsten  compounds  are  used  in  the  manufacture  of 
colors.  The  indicated  consumption  is  approximately  5000  tons  of  60% 
concentrates  per  year,  in  the  United  States. 

Tungsten  is  introduced  into  the  molten  steel  charge,  either  as  the 
powdered  metal  or  as  ferro-tungsten  (containing  50%-85%  tungsten).

VANADIUM 

Bibliography :  Eeport  XV.    Bulletins  67,  91.    Proc.  Colo.  Sci.  Soc, 
Vol.  XI.    U.  S.  Bur.  of  Mines,  Bulletin  104. 

No  commercial  production  of  vanadium  has  yet  been  made  in  Cali- 
fornia. Occurrences  of  this  metal  have  been  found  at  Camp  Signal, 
near  Goffs,  in  San  Bernardino  County,  and  two  companies  at  one  time 
did  considerable  development  work  in  the  endeavor  to  open  up  paying 
quantities.  Each  had  a  mill  under  construction  in  1916,  but  apparently 
no  commercial  output  was  made.  Ore  carrying  the  mineral  cuprodes- 
cloizite  and  reported  as  assaying  4%  VaOg  was  opened  up.  Some  ore 
carrying  lead  vanadate  has  been  developed  in  the  29  Palms,  or  Washing- 
ton district,  on  the  line  between  Riverside  and  San  Bernardino  counties, 
but  no  shipments  reported. 

The  principal  use  of  vanadium  is  as  an  alloy  in  steels,  especially  in 
tool  steel,  and  in  those  varieties  where  resistance  to  repeated  strains  is 
required.  Present  New  York  quotations  for  ferrovanadium  are,  per 
pound  of  vanadium,  f.  o.  b.  works,  $3.15-$3.65,  depending  on  the  grade. 

ZINC 

Bibliography:  State  Mineralogist  Reports  XIV,  XV,  XVII,  XVIII, 
XX,  XXII,  XXIII.    Bulletins  38,  67,  91. 

The  recoverable  zinc  mined  in  California  in  1927  amounted  to 
8,625,004  pounds  valued  at  $552,000  compared  with  20,447,559  pounds 
and  $1,533,568  in  1926.  This  production  came  from  Shasta,  Los 
Angeles  (Santa  Catalina  Island)  and  Riverside  counties  and  was 
shipped  in  the  form  of  concentrates  and  sinter  to  Belgium,  though  a 
small  amount  is  used  in  the  manufacture  of  oxide. 

The  average  price  per  pound  quoted  for  the  metal  in  1927  was  6.4^ 
as  against  7.5^-  in  1926. 

The  zinc  ores  of  Shasta  and  Calaveras  counties  are  associated  with 
copper,  while  those  of  Inyo,  Los  Angeles  and  San  Bernardino  are  asso- 
ciated principally  with  lead-silver  and  zinc-silver  ores. 

The  principal  uses  of  zinc  are  for  'galvanizing'  (plating  on  iron  to 
prevent  rust),  for  zinc  oxide  (used  in  rubber  goods  and  paint),  and  for 
brass  (an  alloy  of  copper  and  zinc).  These  outlets  for  the  metal  take 
approximately  80%  of  the  quantity  produced.    Of  the  remaining  20%

a  large  portion  is  rolled  into  plates  and  sheets,  and  utilized  in  the 
building  industrj^  for  sheathing,  roofing,  leaders,  and  eaves-troughs. 
Zinc  is  particularly  desirable  and  efficient  for  roofing  and  siding  where 
corrosive  gases  are  present,  as  at  smelters,  refineries  and  chemical 
plants. 

Zinc   Production  of  the   United   States. 

The  production  of  slab  zinc  ^  at  reduction  plants  in  the  United  States 
in  1927  amounted  to  576,960  short  tons  valued  at  $73,966,000,  not 
including  15,556  tons  of  primary  metal  made  from  foreign  ores,  mostly 
from  Mexico,  and  reduced  in  refineries  in  this  country.  The  1927 
production  was  a  decline  from  that  of  1926  of  82,261  tons.

STRUCTURAL  MATERIALS 

BiMiograpky :  State  Mineralogist  Reports  XII-XXIII  (inc.). 
Bulletin  38.  Spurr  and  Wormser,  "Marketing  of  Metals  and 
Minerals. "  "  Non-Metallic  Minerals, "  by  R.  B.  Ladoo.  See  also 
under  each  substance. 

As  indicated  by  this  subdivision  heading,  the  mineral  substances 
herein  considered  are  those  more  or  less  directly  used  in  building  and 
structural  work.  California  is  independent,  so  far  as  these  are  con- 
cerned, and  almost  any  reasonable  construction  can  be  made  with  mate- 
rials produced  in  the  state.  This  branch  of  the  mineral  industry  for 
1927  was  valued  at  $54,861,649  as  compared  with  a  total  value  of 
$54,250,571  for  the  year  1926,  the  increase  being  due  to  cement,  granite 
and  sandstone  in  spite  of  a  considerable  decrease  in  miscellaneous  stone, 
brick,  and  magnesite. 

Deposits  of  granite,  marble  and. other  building  stones  are  distributed 
widely  throughout  this  state,  and  transportation  and  other  facilities  are 
gradually  being  extended  so  that  the  growing  demand  may  be  met. 
The  largest  single  item,  cement,  has  had  an  interesting  record  of  growth 
since  the  inception  of  the  industry  in  California  about  1891.  Not  until 
1904  did  the  annual  value  of  cement  produced  reach  the  million-dollar 
mark,  following  which  it  increased  500%  in  nine  years;  though  from 
1914  to  1918  there  was  a  falling  off  common  to  all  building  materials. 
The  1927  output  established  a  new  record  both  in  quantity  and  total 
value,  exceeding  the  previous  total  value  record  made  in  1923  by  over 
a  million  dollars. 

Crushed  rock  production  is  yearly  becoming  more  worthy  of  con- 
sideration, due  to  the  strides  taken  in  the  use  of  concrete,  as  well  as  to 
activity  in  the  building  of  good  roads.  Brick,  with  an  average  annual 
output  for  a  number  of  years  worth  approximately  $2,000,000,  had 
difficulty  in  holding  its  own,  due  to  the  popularity  of  cement  and  con- 
crete. In  1920,  however,  the  sales  increased  to  nearly  double  the 
previous  record  figure  of  the  year  1907,  and  in  1923  showed  advances 
to  new  figures,  with  a  slight  recession  in  1924-1927.  This  item  will,  no 
doubt,  continue  to  be  an  important  one,  and  a  market  for  fire  and  fancy 
brick  of  all  kinds  will  unquestionably  never  be  lacking. 

All  fifty-eight  counties  contributed  to  this  structural  total  for  1926. 
There  is  not  a  county  in  the  state  which  is  not  capable  of  some  output 
of  at  least  one  of  the  materials  under  this  classification. 

During  1927  building  construction  on  the  Pacific  coast  ^  has  declined 
in  the  large  cities  and  increased  in  the  smaller  towns.  The  twenty 
principal  cities  show  a  falling  off'  of  20  per  cent  in  the  total  of  building 
permits. 

The  following  summary  shows  the  value  of  the  structural  materials 
produced  in  California  during  the  years  1926-1927,  with  increases  or 
decreases  in  each  instance.

ASPHALT 

Bibliography :  State  Mineralogist  Reports  VII,  X,  XII-XV  (inc.), 

XVII,  XVIII.    Bulletins  16,  32,  63,  67,  69,  91. 

Asphalt  was  for  a  number  of  years  accounted  for  in  the  statistical 
reports  by  the  State  Mining  Bureau,  because  in  the  early  days  of  the 
oil  industry,  considerable  asphalt  was  produced  from  outcroppings  of 
oil  sand,  and  was  a  separate  industrj'^  from  the  production  of  oil  itself. 
However,  at  the  present  time  most  of  the  asphalt  comes  from  the  oil 
refineries,  which  produce  a  better  and  more  uniform  grade ;  hence,  its 
value  is  not  now  included  in  the  mineral  total,  as  to  do  so  would  be  in 
part  a  duplication  of  the  crude  petroleum  figures.  Such  natural  asphalt 
as  is  at  present  mined  is  in  the  form  of  bituminous  sandstones,  and  is 
recorded  under  that  designation. 

BITUMINOUS   ROCK 

Bibliography :  State  Mineralogist  Reports  XII,  XIII,  XV,  XVII,

This  material  is  essentially  an  uncemented  sandstone  which  is  satur- 
ated with  and  held  together  by  a  natural  asphaltic  constituent,  probably 
the  residue  from  the  evaporation  of  a  crude  petroleum  deposit.  Bitu- 
minous rock  is  still  used  to  a  limited  extent  for  road  dressing  in  those 
districts  adjacent  to  available  deposits,  though  the  manufacture  of 
asphalt  at  the  oil  refineries  has  almost  entirely  superseded  the  direct 
use  of  the  native  material.  The  present  operators  of  the  quarry  near 
the  old  City  Street  Improvement  Company's  property  in  Santa  Cruz 
County  advise  that  they  are  now  putting  on  the  market  a  material 
which  can  be  laid  cold.  It  will  be  especially  applicable  and  valuable 
for  patching  jobs. 

Shipments  from  quarries  in  Santa  Barbara  and  Santa  Cruz  counties 
in  1927  totaled  3515  tons  of  bituminous  rock,  valued  at  $17,704  f .  o  b.

BRICK   AND    HOLLOW   TILE 

Bibliography :  State  Mineralogist  Reports  VIII,  X,  XII-XV  (inc.), 
XVII-XXIII  (inc.).  Bulletins  38,  99.  Preliminary  Report, 
No.  7.    Cal.  Jour,  of  Development,  June,  1925,  pp.  5-6. 

Bricks  of  many  varieties  and  in  important  quantities  are  annually 
produced  in  California,  as  might  be  expected  in  a  state  with  such  diver- 
sified and  widespread  mineral  resources.  The  varieties  include  com- 
mon, fire,  pressed,  glazed,  enamel,  fancy,  vitrified,  sand-lime,  and  others. 
Not  only  do  the  plants  here  supply  practically  all  of  our  own  require- 
ments in  these  products,  but  considerable  quantities  are  shipped  to 
contiguous  territory  and  certain  products  are  shipped  over  a  much 
wider  radius.  So  far  as  possible,  the  different  kinds  have  been  segre- 
gated in  the  tabulation  herewith  accompanying. 

"We  also  include  under  this  heading  the  various  forms  of  hollow 
building  'tile'  or  blocks.  The  application  of  these  tile  to  residence 
construction  as  well  as  to  other  structures  is  growing;  though  their 
total  for  1927  shows  a  drop  from  the  figures  of  1926. 

The  aggregate  value  of  all  kinds  of  brick  in  1927  shows  a  decrease  of 
approximately  7  per  cent  from  that  of  1926,  to  which  each  of  the 
groups  contributed. 

Bulletin  No.  99,  "The  Clay  Resources  and  the  Ceramic  Industry  of 
California,"  published  this  year  (1928)  covers  all  the  brick  plants 
throughout  the  state,  giving  a  detailed  description  of  each. 

The  detailed  figures  of  brick  and  tile  production  for  1927,  by  coun- 
ties, are  shown  in  the  following  tabulation  :

Cement  is  the  most  important  single  structural  material  in  the  min- 
eral output  of  California.  During  1927  there  was  produced  a  total 
of  14,661,783  barrels  valued  at  $26,474,935  f.  o.  b.  plant,  being  an 
increase  of  over  half  a  million  barrels  in  quantity,  and  in  total  value 
although  there  was  a  small  drop  in  prices.  The  1926  output  was 
13,797,173  barrels,  valued  at  $25,269,678,  or  an  average  of  $1.84  per 
barrel.    The  1927  average  was  $1.80  per  barrel. 

The  1927  production  came  from  twelve  operating  plants  in  ten 
counties,  and  employed  a  total  of  3803  men.  The  three  plants  in  San 
Bernardino  County  made  a  total  of  5,557,339  barrels,  valued  at 
$9,823,839,  the  balance  of  the  state's  product  coming  from  a  single 
plant  in  each  of  the  following  counties :  Calaveras,  Contra  Costa,  Kern, 
Merced,  Riverside,  San  Benito,  San  Mateo,  Santa  Cruz,  and  Solano. 
The  new  plant  of  the  Yosemite  Portland  Cement  Company  at  Merced 
began  operations  and  made  commercial  shipments  in  1927.

There  has  been  an  interesting  parallelism  in  the  growth  of  the  port- 
land  cement  and  the  crushed  rock,  sand  and  gravel  industries  in  Cali- 
fornia. The  use  of  concrete  has  been  a  most  important  development  in 
structural  work  during  the  last  20  or  30  years,  and  has  made  possible 
the  building  of  such  great  monolithic  structures  as  our  irrigation  and 
hydroelectric-power  dams,  as  well  as  highway  pavements  and  sky- 
scraper office  buildings. 

In  1927  the  total  production  of  the  United  States  as  given  by  the 
U.  S.  Bureau  of  Mines,  was  171,864,728  barrels  of  portland  cement 
valued  at  $278,854,647,  of  which  approximately  45,000,000  barrels 
were  used  in  the  construction  of  roads  and  streets  in  the  United  States, 
from  which  approximately  6000  miles  of  concrete  rural  roads,  3000 
miles  of  streets,  and  475  miles  of  alleys  were  built. 


Cement  Production  of  California,  by  Years. 

'Portland'  cement  was  first  commercially  produced  in  California  in 
1891 ;  though  in  1860  and  for  several  years  following,  a  natural 
hydraulic  cement  from  Benicia  was  utilized  in  building  operations  in 
San  Francisco. 

^*'The  Benicia  Cement  Company  in  1859-60  was  turning  out  50  to 
100  barrels  of  cement  a  day  and  San  Francisco  was  using  about  12,000 
barrels  a  year.  The  mill  price  of  the  product  was  then  $4  a  barrel.  By 
1865,  the  San  Francisco  rate  of  consumption  had  increased  to  100,000 
barrels  yearly,  brick  buildings  largely  taking  the  place  of  frame  struc- 
tures, and  the  price  of  cement  had  fallen  to  $2.50  a  barrel,  about  the 
same  as  it  is  today." 

The  growth  of  the  industry  became  rapid  after  1902;  since  which 
time  cement  has  continued  to  be  an  important  factor  in  the  industrial 
life  of  the  state.  Although  the  total  cement  figures,  to  date,  are  not 
of  the  same  magnitude  as  those  for  gold  and  petroleum,  it  is  interesting 
to  note  that  the  value  of  California's  cement  yield  beginning  with 
1920  has  since  annually  exceeded  the  value  of  her  gold  output. 

Annual  production  of  cement  in  California  has  been  as  follows :

72  MINERAL    INDUSTRY    OF    CALIFORNIA 

CHROMITE 

Bibliography:  State  Mineralogist  Reports  IV,  XII,  XIII,  XIV, 
XV,  XVII,  XVIII,  XXI-XXIII.  Bulletins  38,  76,  91.  Prelim- 
inary Report  3.  U.  S.  G.  S.,  Bull.  430.  Min.  &  Sci.  Press,  Vol. 
114,  p.  552. 

Chromic  iron  ore,  or  chromite,  to  the  amount  of  225  short  tons 
recalculated  to  the  basis  of  45%  Ci-oOg,  valued  at  $5,063  f .  o.  b.  ship- 
ping point,  was  sold  during  the  year  1927  in  California,  This  was 
largely  of  ore  that  had  been  mined  during  the  World  War  period  but 
not  then  sold.  It  is  hoped  that  the  development  of  the  steel  industry 
and  the  resumption  of  copper  smelting  on  the  Pacific  Coast  may  create 
some  demand  for  California's  chromite,  but  the  outlook  for  the  imme- 
diate future  is  not  encouraging. 

The  political  and  commercial  control  of  chromite  now  rests  largely 
with  England,  through  the  ownership  and  sales  contracts  exercised  by 
the  Chrome  Company  (Ltd.),  of  London.  That  company  controls  both 
the  Rhodesian  and  the  New  Caledonian  output. 

Ocourrence. 

Until  1916,  when  some  shipments  were  made  from  Oregon  and 
smaller  amounts  from  I\Iaryland,  Wyoming  and  Washington,  practi- 
cally our  only  domestic  production  of  chromite  for  many  j'ears  came 
from  California.  From  1830  to  1870  the  deposits  in  Maryland  supplied 
the  world's  consumption. 

Chromite  is  widely  distributed  in  California,  the  principal  produc- 
tion, thus  far,  having  come  from  El  Dorado,  San  Luis  Obispo,  Del 
Norte,  Shasta,  Siskiyou,  Placer,  Fresno,  and  Tuolumne  counties.  In 
1918  a  total  of  29  counties  contributed  to  the  state's  output.  There 
are  two  main  belts  in  California  yielding  this  mineral,  one  along  the 
Coast  Ranges  from  San  Luis  Obispo  County  to  the  Oregon  line,  includ- 
ing the  Klamath  Mountains  at  tlie  north  end.  and  the  other  in  the  Sierra 
Nevada  from  Tulare  County  to  Plumas  County.  Chromite  occurs  as 
lenses  in  basic  igneous  rocks  such  as  peridotite  and  pyroxenite,  and  in 
serpentines  which  have  been  derived  by  alteration  of  such  basic  rocks. 
For  the  most  part,  so  fas  as  developments  have  yet  sho-^^Ti,  the  lenses 
liave  proved  to  be  small,  relatively  few  of  them  yielding  over  100  tons 
apiece.  A  notable  exception  to  tliis  was  the  deposit  on  Little  Castle 
Creek,  near  Dunsmuir,  from  which  upwards  of  15,000  tons  were  shipped 
before  it  was  exhausted.  Deposits  worked  in  Del  Norte  County  during 
1918  promise  well  for  a  large  tonnage.  On  the  whole  the  orebodies  in 
the  northwestern  corner  of  the  state  appear  to  average  larger  in  size 
than  the  chromite  lenses  in  other  parts  of  California. 

Concentration  became  an  accomplished  fact  in  several  localities,  thus 
utilizing  some  of  the  disseminated  and  lower-grade  orebodies  which 
liave  been  found.  In  fact,  an  important  part  of  the  1918-1920  produc- 
tion of  California  came  from  that  source. 

Imports. 

Importations  of  foreign  chromite,  duty  free,  mainly  from  Rhodesia, 
New  Caledonia,  and  India,  totaled  222,360  long  tons  in  1927,  valued  at 
$1,738,598,  compared  with  215,464  long  tons  and  $1,704,947  in  1926.

Use^. 

The  major  consumption  of  cliromite  ore  is  for  use  as  a  refractory 
lining  in  smelting  furnaces  for  steel  and  copper.  A  smaller  portion 
is  used  in  the  preparation  of  ferrochrome  for  chrome-steel  alloys,  and 
of  chromium  chemicals,  the  latest  development  of  which  is  chrome 
plating  as  used  in  the  automobile  industry,  on  ships,  and  in  oil  refin- 
eries to  protect  metal  surfaces  from  wear  and  erosion.  It  is  stated 
that  during  the  last  three  years,  the  sales  of  chromite  brick  and 
chromite  cement  have  increased  500%,  because  of  their  replacing 
magnesite  which  is  more  expensive. 


Total  Chromite  Production  of  California. 

Production  of  chromite  in  California  began,  apparently,  about  1874, 
principally  in  San  Luis  Obispo  County.  There  Avas  considerable  activ- 
ity from  1880  to  1883,  inclusive,  and  a  total  of  23,238  long  tons  (or 
26,028  short  tons),  valued  at  $329,924  was  shipped  from  that  county 
up  to  the  beginning  of  1887.  Some  ore  also  was  shipped  from  the 
Tyson  properties  in  Del  Norte  County.  The  tabulation  herewith  shows 
the  output  of  chromite  in  California,  annually,  including  the  earliest 
figures  so  far  as  they  are  available.  The  figures  from  1887  to  date  are 
from  the  records  of  the  State  Mining  Bureau :

of  $1,853,859  in  1925.  We  have  included  under  this  heading  some 
rhyolite  and  tuff  utilized  for  dimension  building  stone,  as  we  have 
no  other  dimension-stone  grouping  for  statistical  purposes  in  this  report 
except  marble  and  sandstone. 

So  far  as  possible,  granite  production  has  been  segregated  in  the 
table  herewith  into  the  various  uses  to  which  the  product  was  put.    It

will  be  noted,  however,  that  a  portion  of  the  output  has  been  entered 
under  the  heading  '  Unclassified. '  This  is  necessary  because  of  the  fact 
that  some  of  the  producers  have  no  way  of  telling  to  what  specific  use 
their  stone  was  put  after  they  had  quarried  and  sold  the  same  in  the 
rough. 

Varieties. 

For  building  purposes,  the  granites  found  in  California,  particularly 
the  varieties  from  Raymond  in  Madera  County,  Rocklin  in  Placer 
County,  and  near  Porterville  in  Tulare  County,  are  unexcelled  by  any 
similar  stone  found  elsewhere.  The  quantities  available,  notably  at 
Raymond  and  Porterville,  are  unlimited.  Most  of  California's 
'granite,'  particularly  that  found  in  the  Sierra  Nevada  Mountains,  is 
technically  '  granodiorite '  (that  is,  both  plagioclase  and  orthoclase 
feldspars  are  present). 

Granites  of  excellent  quality  for  building  and  ornamental  purposes 
are  also  quarried  in  Riverside  and  San  Diego  counties.  Near  Lakeside, 
San  Diego  County,  there  is  a  fine-grained,  'silver  gray'  granite  of 
uniform  texture  and  color,  especially  suited  for  monumental  and 
ornamental  work. 

The  Fresno  County  stone  is  a  dark,  hornblende  diorite,  locally  called 
'black  granite,'  whose  color  permits  of  a  fine  contrast  of  polished  and 
unpolished  surfaces,  making  it  particularly  suitable  for  monumental 
and  decorative  purposes.  There  is  also  a  similar  'black  granite'  in 
Tulare  County,  near  Success.

LIME 

BihUography :  Reports  XIV,  XV,  XVII,  XVIII.    Bulletin  38. 

Lime  to  the  amount  of  60,498  tons,  valued  at  $631,497,  was  produced 
by  nine  plants  in  seven  counties  during  1927,  as  compared  with 
63,568  tons,  valued  at  $670,837,  in  1926.  There  were  two  plants  each  in 
San  Bernardino  and  Santa  Cruz  counties,  and  one  each  in  Inyo,  Kern, 
Plumas,  Tulare,  and  Tuolumne. 

So  far  as  we  have  been  able  to  segregate  the  data,  these  figures  include 
mainly  only  such  lime  as  is  used  in  building  operations ;  though  they  do 
include  a  small  proportion  of  calcined  lime  employed  in  agriculture 
and  the  chemical  industries,  the  figures  for  which  were  not  separable. 
A  portion  is  hydrated  lime.  Limestone  utilized  in  sugar  making,  for 
smelter  flux,  as  a  fertilizer,  and  other  special  industrial  uses,  are  classi- 
fied under  'Industrial  Materials.'  That  consumed  in  cement  manufac- 
ture is  included  in  the  value  of  cement. 

Lime  Production  of  California,  by  Years. 

The  following  tabulation  gives  the  amounts  and  value  of  lime  pro- 
duced in  California  by  years  since  1894  when  compilation  of  such 
records  was  begun  by  the  State  Mining  Bureau.  The  figures  for 
quantitv  have  been  recalculated  from  'barrels'  to  'tons'  for  the  years 
1894-1922  (inc.)  :

Magnesite.  A  Preliminary  Statement  of  Information,"  May  19, 
1926. 

The  production  of  magnesite  in  California  during  1927  amounted  to 
a  total  of  46,093  tons  of  crude  ore,  valued  at  $577,887.  Only  a  small 
part  of  it  was  sold  'crude,'  however,  as  it  is  practically  all  shipped  in 
the  calcined  form.  The  reports  at  hand  shoAv  a  total  of  19,277  tons 
shipped  calcined,  including  a  small  tonnage  dead-burned  for  refractory 
purposes,  the  balance  going  to  the  plastic  trade.  From  2  to  2^  tons 
of  crude  material  are  mined  to  make  one  ton  of  calcined.  The  1927 
output  is  a  decrease  both  in  quantity  and  value  from  the  1926  figures 
of  50,915  tons  crude  valued  at  $587,642.  The  average  of  the  values 
reported  for  1927  is  $12.50  per  ton  compared  with  $11.60  in  1926. 
There  were  two  operators  who  produced  1300  tons  of  crude  but  who 
had  not  shipped  any  during  1927  though  they  expect  to  do  so  in  1928. 

Occurrence. 

Magnesite  is  a  natural  carbonate  of  magnesium,  and  when  pure  con- 
tains 52.4%  COo  (carbon  dioxide),  and  47.6%  MgO  (magnesia).  It  has 
a  hardness  of  3.5  to  4.5,  and  specific  gravity  of  3  to  3.12.  It  is  both 
harder  and  heavier  than  calcite  (calcium  carbonate),  and  also  contains 
a  higher  percentage  of  CO2  as  calcite  has  but  44%. 

Most  of  the  Californian  magnesite  is  comparatively  pure,  and  is  ordi- 
narily a  beautiful,  white,  fine-grained  rock  with  a  conchoidal  fracture 
resembling  a  break  in  porcelain.  The  Grecian  magnesite  is  largely  of 
this  character ;  but  the  Austrian  varieties  usually  contain  iron,  so  that 
they  become  brown  after  calcining.    The  Washington  magnesite  resem- 


78  MINERAL  INDUSTRY  OP  CALIFORNIA 

bles  dolomite  and  some  crystalline  limestones  in  physical  appearance. 
Its  color  varies  through  light  to  dark  gray,  and  pink. 

In  California  the  known  deposits  are  mostly  in  the  metamorphic 
rocks  of  the  Coast  Ranges  and  the  Sierra  Nevada,  being  associated 
with  serpentine  areas.  The  notable  exceptions  are  the  sedimentary 
deposits,  at  Bissell  in  Kern  County  and  at  Afton  in  San  Bernardino 
County.  Several  thousand  tons  have  been  shipped  from  the  Bissell 
deposit ;  and  small  shipments  have  been  made  from  the  Afton  property. 

The  Washington  deposits  are  associated  with  extensive  strata  of 
dolomite  limestone.  The  magnesite  there  appears  to  contain  more  iron 
than  most  of  the  California  mineral,  which  makes  it  desirable  for  the 
steel  operators.  However,  recent  experience  has  proved  that  several 
California  localities  have  sufficient  iron  in  their  magnesite  to  be  service- 
able in  the  steel  furnaces. 

Uses. 

The  principal  uses  include :  Refractory  linings  for  basic  open-hearth 
steel  furnaces,  copper  reverberatories  and  converters,  bullion  and  other 
metallurgical  furnaces ;  in  the  manufacture  of  paper  from  wood  plup  ; 
and  in  structural  work,  for  exterior  stucco,  for  flooring,  wainscoting, 
tiling,  sanitary  kitchen  and  hospital  finishing,  etc.    In  connection  with 
building  work  it  has  proved  particularly  efficient  as  a  flooring  for  steel 
railroad  coaches,  on  account  of  having  greater  elasticity  and  resilience 
than  'Portland'  cement.     For  refractory  purposes  the  magnesite  is 
'dead-burned' — i.  e.,  all  or  practically  all  of  the  COj  is  expelled  from  it. 
For  cement  purposes  it  is  left  'caustic' — i.  e.,  from  2%  to  10%  of  COo 
is  retained.     When  dry  caustic  magn&site  is  mixed  with  a  solution  of 
magnesium   chloride    (MgCl,)    in   proper  proportions,   a  very  strong  | 
cement  is  produced,   known  as  oxychloride  or   Sorel  cement.     It  isj 
applied  in  a  plastic  form,  which  sets  in  a  few  hours,  as  a  tough,  seamless 
surface.     It  has  also  a  very  strong  bonding  power,  and  will  hold  firmb 
to  wood,  metal,  or  concrete  as  a  base.     It  may  be  finished  with  a  verj 
smooth,  even  surface,  which  will  take  a  good  wax  or  oil  polish.     As 
ordinarily  mixed  there  is  added  a  certain  proportion  of  wood  flourJ 
cork,  asbestos,  or  other  filler,  thereby  adding  to  the  elastic  properties  of 
the  finished  product.     Its  surface  is  described  as  'warm'  and  'quiet] 
as  a  result  of  the  elastic  and  nonconducting  character  of  the  composite 
material.     The  cement  is  frequently  colored  by  the  addition  of  some 
mineral  pigment  to  the  materials  before  mixing  as  cement. 

For  refractory  purposes  the  calcined  magnesite  is  largely  made  uj 
into  bricks  similar  to  fire-brick  for  furnace  linings.  It  is  also  usee 
unconsolidated,  as  'grain'  magnesite.  For  such,  an  iron  content  \i 
desirable,  as  it  allows  a  slight  sintering  in  forming  the  brick.  Dead-j 
burned,  pure  magnesia  can  not  be  sintered  except  at  very  high  temperaj 
tures ;  and  it  has  little  or  no  plasticity,  so  that  it  is  hard  to  handle.  It^ 
plasticity  is  said  to  be  improved  by  using  with  it  some  partly  calcinee 
or  caustic  magnesite.  Heavy  pressure  will  bind  the  material  sufficiently 
to  allow  it  to  be  sintered. 

A  coating  of  crushed  magnesite  is  laid  on  hearths  used  for  heating 
steel  stock  for  rolling,  to  prevent  the  scale  formed  from  attacking  th^ 
fire-brick  of  the  hearth. 


STATISTICS   OF    ANNUAL   PRODUCTION 


79 


Before  the  World  War,  practically  all  of  the  domestic  output  of 
caustic  magnesite  was  used  in  the  manufacture  of  pulp  and  paper.  For 
this  purpose  calcined  dolomite  is  now  used.  The  use  of  dolomite 
instead  of  magnesite  by  paper  manufacturers  began  during  the  war 
when  the  price  of  magnesite  was  very  high.  Dolomite  was  found  to 
be  a  good  substitute  for  magnesite  in  the  bisulphite  process  of  paper 
making  and  so  its  use  has  continued. 

Fmports. 

The  Tariff  Act  of  1922,  which  became  effective  September  22d,  of 
that  year,  placed  the  following  import  duties  on  magnesite :  Crude 
magnesite  %6^  per  lb.,  caustic-calcined  magnesite  %^  per  lb. ;  dead- 
burned  and  grain  magnesite,  not  suitable  for  manufacture  into  oxy-

ad  valorem.  The  figures  of  imports  for  1927,  as  published  by  the  U.  S. 
Bureau  of  Foreign  and  Domestic  Commerce,  show  a  total  of  60,224 
short  tons  of  calcined  ore,  valued  at  $959,483,  as  compared  with  92,546

Total   Magnesite  Production  of  California. 

The  first  commercial  production  of  magnesite  in  California  was  made 
in  the  latter  part  of  1886  from  the  Cedar  Mountain  district,^  southeast 
of  Livermore,  Alameda  County.  Shipments  amounting  to  'several 
tons'  or  'several  carloads'  were  sent  by  rail  to  New  York;  but  there  is 
apparently  no  exact  record  of  the  amount  for  that  first  year.  The 
statistical  records  of  the  State  Mining  Bureau  began  with  the  year 
1887,  and  the  table  herewith  shows  the  figures  for  amount  and  value, 
annually,  from  that  time.  Shipments  of  magnesite  from  Napa  County 
began  in  1891  from  the  Snowflake  Mine;  from  the  Red  Mountain 
deposits  in  Santa  Clara  County,  in  1899;  and  from  Tulare  County 
in  1900.

MINERAL    INDUSTRY    OP    CALIFORNIA 


MARBLE 

Bibliography:  State  Mineralogist  Reports  XII-XV  (inc.),  XVII-

Marble  is  widely  distributed  in  California,  and  in  a  considerable 
variety  of  colors  and  grain.  The  1927  figures  show  a  slight  decline  in 
both  quantity  and  value  from  those  of  1926,  and  are  combined  with 
onyx  and  travertine  to  conceal  the  output  of  a  single  operator. 

California  has  many  beautiful  and  serviceable  varieties  of  marble, 
suitable  for  almost  any  conceivable  purpose  of  construction  or  decora- 
tion. In  the  decorative  class  are  deposits  of  onyx  marble  of  beautiful 
coloring  and  effects.  There  is  also  serpentine  marble  suitable  for  elec- 
trical switchboard  use.

Onyx  and  travertine  are  known  to  exist  in  a  number  of  places  in 
California,  but  there  has  been  only  a  small  and  irregular  production 
since  the  year  1896.  In  1927  there  were  shipments  from  Kern,  River 
side,  San  Bernardino,  and  Solano  counties  with  an  increase  in  both 
quantity  and  value,  the  figures  of  which  are  combined  with  marble. 
This  material  is  used  in  terrazzo,  auto  gear-shift  handles,  bases  for 
fountain-pen  desk  sets,  and  other  ornamental  purposes.

BiUiography :  State  Mineralogist  Reports  XII-XV,  XVII,  XVIII, 
XXI.    Bulletin  38.    U.  S.  Bur.  of  M.,  Bull.  124. 

An  unlimited  amount  of  high-grade  sandstone  is  available  in  Cali- 
fornia, but  the  wide  use  of  concrete  in  buildings  of  every  character,  as 
well  as  the  popularity  of  a  lighter-colored  building  stone,  has  curtailed 
production  in  this  branch  of  the  mineral  industry  during  recent  years 
almost  to  the  vanishing  point.  In  1927  a  total  of  22,900  cu.  ft.,  valued 
at  $205,400,  was  quarried  in  five  counties,  Monterey,  Napa,  Santa 
Barbara,  Siskiyou  and  Sonoma;  compared  with  34,100  cu.  ft.  and 
$17,500  in  1926.  The  material  reported  from  Monterey  County  is  in 
reality  an  indurated  shale  of  the  Monterey  series,  of  a  cream  color  and 
utilized  as  a  building  stone ;  and  that  from  Sonoma  is  a  stratified, 
altered  andesite  having  the  appearance  of  sandstone. 

A  large  portion  of  the  sandstone  was  sold  for  landscape  work  and 
used  as  stepping  stones  for  walks  and  for  fountains,  walls,  etc.

82  MINERAL    INDUSTRY    OF    CALIFORNIA 

SLATE 

Bibliography:    State  Mineralogist  Reports  XV,  XVIII.     Bulletin 
38.    U.  S.  Geol.  Surv.,  Bull.  586.    U.  S.  Bur.  of  Mines,  Bull.  218. 

Slate  was  first  produced  in  California  in  1889.  Up  to  and  including 
1910  such  production  was  continuous,  but  since  then  it  has  been  irregu- 
lar. Large  deposits  of  excellent  quality  are  known  in  the  state,  espe- 
cially in  El  Dorado,  Calaveras  and  Mariposa  counties,  but  the  demand 
has  been  light  owing  principally  to  competition  of  cheaper  roofing 
materials. 

'Slate'  is  a  term  applied  to  a  fine-grained  rock  that  has  a  more  or 
less  perfect  cleavage,  permitting  it  to  be  readily  split  into  thin,  smooth 
sheets.  Varieties  differ  widely  in  color  and  have  a  considerable  range 
in  chemical  and  mineralogical  composition.  Excepting  certain  rare 
slates  of  igneous  origin  (of  which  the  green  slate  of  the  Eureka  quarry. 
El  Dorado  County,  California,  is  an  example)  formed  from  volcanic 
ash  or  igneous  dikes,  slates  have  originated  from  sedimentary  deposits 
consisting  largely  of  clay.  By  consolidation,  and  the  pressure  of  super- 
imposed materials,  clays  become  bedded  deposits  of  shale.  By  further 
consolidation  under  intense  pressure  and  high  temperature  incident  to 
mountain-building  forces,  shales  are  metamorphosed  to  slates.  The 
principal  mineral  constituents  are  mica,  quartz,  and  chlorite,  with 
smaller  varying  amounts  of  hematite,  rutile,  kaolin,  graphite,  feldspar, 
tourmaline,  calcite,  and  others. 

The  color  of  slate  is  of  economic  importance.  The  common  colors  are 
gray,  bluish  gray,  and  black,  though  reds  and  various  shades  of  green 
are  occasionally  found. 

The  permanency  of  slate  for  roofing  is  well  known.  It  is  stated  that 
there  are  slate  roofs  in  Pennsylvania  and  Maryland  over  100  years  old. 

^  "In  Engrland  and  Wales,  and  in  France,  many  buildings  constructed  in  the  15th 
and  16th  centuries  were  roofed  with  slate,  and  the  roofs  are  still  in  excellent  condi- 
tion. There  is  a  record  of  a  chapel  in  Bedford-on-Avon  in  Wiltshire,  England,  roofed 
with  slate  in  the  8th  century,  and  after  1200  years  of  climatic  exopsure  is  moss- 
covered  but  in  good  condition." 

Contrary  to  the  general  impression,  however,  the  major  portion  of 
the  slate  produced  in  the  United  States  is  used  on  the  inside  rather  than 
the  outside  of  buildings.  Its  interior  uses  include  stationary  washtubs, 
electrical  switchboards,  and  blackboards. 

A  square  of  roofing  slate  is  a  sufficient  number  of  pieces  of  any  size 
to  cover  100  square  feet  of  roof,  with  allowance  generally  for  a  three- 
inch  lap.  The  sizes  of  the  pieces  of  slate  making  up  a  square  range 
from  7x9  inches  to  16  x  24  inches,  and  the  number  of  pieces  in  a 
square  ranges  from  85  to  686.  The  Ferry  Building,  San  Francisco,  is 
roofed  with  Eureka  slate  from  El  Dorado  County. 

In  California  there  were  shipments  in  1927  amounting  to  2686  tons 
valued  at  $17,960  from  El  Dorado,  Mariposa  and  Tuolumne  counties. 
This  was  an  increase  over  the  1926  output  valued  at  $7,371.  Most  of 
this  slate  was  crushed  and  used  for  roofing  granules.

MISCELLANEOUS   STONE 

Bibliography:  State  Mineralogist  Reports  XII-XXIII  (inc.)-  Bul- 
letin 38 ;  also  annual  statistical  bulletins  from  1915  to  date. 

'Miscellaneous  stone'  is  the  name  used  throughout  this  report  as  the 
title  for  that  branch  of  the  mineral  industry  covering  crushed  rock  of 
all  kinds,  paving  blocks,  sand  and  gravel,  and  pebbles  for  grinding 
mills.  The  foregoing  are  very  closely  related  from  the  standpoint  of 
the  producer;  therefore  it  has  been  found  to  be  most  satisfactory  to 
group  these  items  as  has  been  done  in  recent  reports  of  this  Bureau. 
So  far  as  it  has  been  possible  to  do  so,  crushed  rock  production  has 
been  subdivided  into  the  various  uses  to  which  the  product  was  put.  It 
will  be  noted,  however,  a  very  large  percentage  of  the  output  has  been 
tabulated  under  the  heading  'Unclassified.'  This  is  necessary  because 
of  the  fact  that  many  of  the  producers  have  no  way  of  telling  to  what 
specific  use  their  rock  was  put  (or  at  least  the  proportions  to  each  use) 
after  they  have  quarried  and  sold  the  same  to  distributors  and  con- 
tractors. 

In  addition  to  amounts  produced  by  commercial  firms,  both  corpo- 
rations and  individuals,  there  is  hardly  a  county  in  the  state  but  uses 
more  or  less  gravel  and  broken  rock  on  its  roads.  Of  much  of  this, 
particularly  in  the  country  districts,  there  is  no  definite  record  kept. 

For  the  year  1927  the  production  of  crushed  rock  registered  a  gain 
both  in  tonnage  and  value  over  the  preceding  year.     Sand  and  gravel 
tonnage  remained  practically  the  same,  although  there  was  a  drop  in 
their  value.     This  resulted  in  a  total  value  of  $18,911,194,  being  a- 
decrease  from  $19,859,873  in  1926. 

.  As  for  some  years  past,  Los  Angeles  County  led  all  others  by  a  wide 
margin  with  an  output  valued  at  $6,292,078  (compared  with  $7,472,- 
884  in  1926);  followed  by  Alameda,  second,  with  $1,538,017;  River-

Paving   Blocks. 

The  paving  block  industry  has  decreased  materially  of  recent  years,! 
practically  to  the  vanishing  point,  because  of  the  increased  construction" 
of  smoother  pavements  demanded  by  motor  vehicle  traffic.  The  blocks 
made  in  Solano  County  were  of  basalt ;  those  from  Sonoma  are  of  basalt, 
andesite,  and  some  trachyte,  while  those  from  Madera,  Placer,  River- 
side, San  Bernardino,  and  San  Diego  are  of  granite. 

The  amount  and  value  of  paving  block  production,  annually,  since 
1887  has  been  as  follows :

•Figures  for  1887-1892  (inc.)  are  for  Sonoma  County  only,  as  none  are  available  for  other  counties  during  that  period 
though  Solano  County  quarries  were  then  also  quite  active. 


Grinding    Mill    Pebbles. 

Production  of  pebbles  for  tube  and  grinding  mills  began  commer- 
cially in  California  in  1915.  Owing  to  the  decreased  imports  and 
higher  prices  of  Belgium  and  other  European  flint  pebbles,  due  to  the 
war,  there  was  a  serious  inquiry  for  domestic  sources  of  supply.  In 
1916  and  1917  shipments  totaled  in  excess  of  20,000  tons  per  year;  but 
they  have  since  dropped  to  an  insignificant  figure.  San  Diego  County 
has  been  the  principal  contributor,  with  some  also  from  Fresno  and 
Sacramento.  Shipments  have  been  made  to  metallurgical  plants  in 
California,  Nevada,  Montana  and  Utah. 

Imports  in  1927  amounted  to  13,563  long  tons,  valued  at  $93,658 
compared  with  13,474  long  tons  and  $120,078  in  1926. 

California  output  for  1927  was  288  tons,  valued  at  $1,800,  an 
increase  from  the  1926  figures.

Sand  and  Gravel. 

A  considerable  part  of  the  gravel  excavated  is  passed  through  grading 
and  washing  plants,  and  the  material  over  2  inches  in  size  is  crushed. 
Much  of  it  is  utilized  in  concrete  mixtures.  Most  of  the  gravel  used  for 
road  surfacing  and  repairs  as  well  as  that  for  railroad  ballast  is  creek- 
run  or  pit-run  material  which  is  spread  upon  the  roads  without  under- 
going any  grading  or  washing. 

The  distribution  of  the  1927  output  of  sand  and  gravel,  .by  counties,

MINflfeAL    INDUSTRY    OF    CALIFORNIA 


Included  in  the  above  is  a  total  of  46,930  tons  of  molding  sand, 
valued  at  $128,752  f .  o.  b.  pit  from  two  operators  each  in  Riverside  and 
San  Diego  counties,  and  one  each  in  Alameda,  Contra  Costa,  Sacra- 
mento, San  Francisco,  San  Luis  Obispo  and  Ventura.  This  item  is 
each  year  assuming  a  more  important  position  in  the  commercial 
mineral  list  of  California.  The  1926  figures  totaled  46,601  tons  and 
$105,336. 

Crushed   Rock. 

To  list  the  kinds  and  varieties  of  rock  utilized  commercially  under 
this  heading  would  be  to  run  almost  the  entire  gamut  of  the  classifica- 
tion scale.  Much  depends  on  the  kind  available  in  a  given  district. 
Those  which  give  the  most  satisfactory  service  are  the  basalts  and  other 
hard,  dense,  igneous  rocks  which  break  with  sharp,  clean  edges.  In 
many  localities,  river-wash  boulders  form  an  important  source  of  such 
material.  In  such  cases,  combined  crushing  and  washing  plants  obtain 
varying  amounts  of  sand  and  gravel  along  with  the  crushed  sizes.  In 
Sacramento  and  Butte  counties  the  tailings  piles  from  the  gold  dredgers 
are  the  basis  of  like  operations. 

The  values  given  are  based  on  the  selling  prices,  f .  o.  b.  cars,  barges, 
or  trucks,  at  the  quarry.

A  comparison  of  the  above  table  of  annual  production  of  these  mate- 
rials with  the  similar  table  for  cement  (see  ante),  reveals  the  fact  that 
the  important  growth  of  the  crushed  rock  and  gravel  business  has  been 
coincident  with  the  rapid  development  of  the  cement  industry  from  the 
year  1902.

INDUSTRIAL  MATERIALS

and  Wormser,  "Marketing  of  Metals  and  Minerals."  "Non- 
Metallic  Minerals,"  by  R.  B.  Ladoo.  See  also  under  each 
substance. 

The  following  mineral  substances  have  been  arbitrarily  arranged 
under  the  general  heading  of  'Industrial  Materials,'  as  distinguished 
from  those  which  have  a  clearly  defined  classification,  such  as  metals, 
salines,  structural  materials,  etc. 

These  materials,  many  of  which  are  mineral  earths,  are,  with  four  or 
five  exceptions,  as  yet  produced  on  a  comparatively  small  scale.  The 
possibilities  of  development  along  several  of  these  lines  are  large,  and 
Avitli  increasing  transportation  and  other  facilities,  together  with  stead- 
ily growing  demands,  the  future  for  this  branch  of  the  mineral  industry 
in  California  is  promising.  There  is  scarcely  a  county  in  the  state  but 
might  contribute  to  the  output. 

Up  to  within  the  last  few  years,  at  least,  production  has  been  in  the 
majority  of  instances  dependent  upon  more  or  less  of  a  strictly  local 
market,  and  the  annual  tables  show  the  results  of  such  a  condition,  not 
only  in  the  widely-varying  amounts  of  a  certain  material  produced 
from  year  to  year,  but  in  widely-varying  prices  of  the  same  material. 

The  more  important  of  these  minerals  thus  far  exploited,  so  far  as 
shown  by  value  of  the  output,  are  limestone,  mineral  water,  pyrites, 
pottery  clays,  diatomaceous  earth,  gj^psum,  talc,  dolomite,  fuller's 
earth. 

This  gToup  as  a  whole  showed  an  increase  in  the  total  value  to 
$5,258,068  in  1927  from  $4,675,924  for  1926. 

The  following  table  gives  the  comparative  figures  for  the  amounts 
and  value  of  industrial  minerals  produced  in  California  during  the 
years  1926  and  1927  :

ASBESTOS

69.  Min.  &  Sci.  Press,  April  10,  1920,  pp.  531-533.  Eng.  &  Min.

In  1927  there  was  a  small  tonnage  of  crude  asbestos  ore  and  fibre 
produced  in  California,  but  as  there  was  only  a  single  operator,  the 
figures  are  concealed  under  the  'Unapportioned'  item. 

The  future  of  asbestos  mining  in  California  is  dependent  largely 
upon  the  development  of  uses  in  quantity  for  the  short-fibre  mill 
grades,  and  for  the  amphibole  variety.  There  are  apparently  large 
resources  of  such  material  that  can  be  made  available.  Some  spinning- 
grade  fibre  has  also  been  found  in  this  state,  notably  in  Nevada,  Cala- 
veras, and  Monterey  counties,  but  the  commercial  yield  to  date  has  been 
small.  There  are  extensive  serpentine  areas  in  the  Coast  Ranges,  in 
the  Klamath  Mountains,  and  in  several  sections  of  the  Sierra  Nevada 
which  are  within  the  range  of  possible  asbestos  producers,  as 
chrysotile  is  a  fibrous  form  of  serpentine.  These  localities  all  yielded 
chromite  in  greater  or  less  amounts  during  the  World  War  period. 

Three-quarters  of  the  world's  supply  of  asbestos  was  for  many  years 
produced  by  Canada. 

At  present,  Rhodesia  furnishes  60  per  cent  of  the  long  fibre,  though 
Canada  in  addition  to  its  long  fibre  still  accounts  for  practically  the 
entire  output  of  lower  grades.

amounted  to  a  total  of  17,993  tons,  valued  at  $90,617  f .  o,  b,  rail- 
shipping  point,  being  a  marked  increase  in  both  quantity  and  value 
over  the  1926  figures  of  4978  tons  and  $38,165.  The  1927  yield  came 
from  properties  in  Mariposa,  Nevada  and  Orange  counties.  The 
bar^'tes  from  Mariposa  and  Nevada  counties  was  consumed  principally 
in  the  manufacture  of  lithopone.  That  from  Orange  County  was  a 
furnace  sinter,  being  a  barytes  gangue  in  a  quiclcsilver  ore,  and  was 
sold  for  use  in  oil-well  drilling  mud. 

More  than  half  of  the  total  tonnage  of  barytes  utilized  in  the  United 
States  is  taken  in  the  manufacture  of  lithophone,  which  is  a  chemically- 
prepared  white  pigment  containing  approximately  70%  barium  sulphate 
and  30%  zinc  sulphide.  This  is  one  of  the  principal  constituents  of 
'flat'  wall  paints.  Other  important  uses  for  barytes,  after  washing 
and  grinding,  are  as  an  inert  pigment  and  filler  in  paint,  paper,  lino- 
leums, oilcloth  and  rubber  manufacture,  and  in  the  preparation  of  a 
number  of  chemicals  including  barium  binoxide,  carbonate,  chloride, 
nitrate,  and  the  sulphate  precipitated,  or  'blanc  fixe.' 

Present  quotations  for  barytes  vary  from  $7  to  $9  per  ton,  crude, 
f.  0.  b.  rail-shipping  point,  depending  on  quality.  Most  baryte  has  to 
be  washed  and  acid  treated  to  remove  iron  stains  or  other  impurities 
before  being  suitable  for  paint  use. 

Known  occurrences  of  this  mineral  in  California  are  located  in  Inyo, 
Los  Angeles,  Mariposa,  Monterey,  Nevada,  San  Bernardino,  Shasta  and 
Santa  Barbara  counties.  The  deposit  at  El  Portal,  in  Mariposa  County, 
has  given  the  largest  commercial  production  to  date,  in  part  witherite 
(barium  carbonate,  BaCOg).  Witherite  has  also  been  found  in  Shasta 
County,  but  no  shipments  have  yet  been  made  from  the  deposit. 

Total    Barytes   Production  of  California. 

The  first  recorded  production  of  barytes  in  California,  according  to 
the  statistical  reports  of  the  State  Mining  Bureau,  was  in  1910.  The 
annual  figures  are  as  follows :

several  different  clay.s,  and  that  these  are  not  all  found  in  the  same

counties  from  which  the  raw  material  originated;  and  have  deducted 
tonnages  used  in  brick  manufacture,  as  bricks  are  classified  separately,

DIATOMACEOUS    EARTH 

Bibliography:  State  Mineralogist  Reports  II,  XII-XV  (inc), 
XVII-XXII  (inc.).  Bulletins  38,  67,  91.  Am.  Inst.  Min. 
Eng.,  Bull.  104,  August,  1915,  pp.  1539-1550.  U.  S.  Bur.  of 
Mines,  Rep.  of  Investigations :  Serial  No.  2431,  Jan.,  1923.  Eng. 
&  Min.  Jour.-Press,  Vol.  115,  pp.  1152-1154,  June  30,  1923. 

Infusorial  and  diatomaceous  earths — sometimes  called  tripolite — are 
very  light  and  extremely  porous,  chalk-like  materials  composed  of  pure 
silica  (chalk,  being  calcareous)  which  have  been  laid  down  under  water 
and  consist  of  the  remains  of  microscopical  infusoria  and  diatoms. 
The  former  are  animal  remains,  and  the  latter  are  from  plants.  The 
principal  commercial  use  of  diatomaceous  earth  (also  called  'diatomite') 
is  as  an  absorbent.  It  is  also  employed  in  the  manufacture  of  scouring 
soap  and  polishing  powders;  for  filtration  purposes;  in  making  some 
classes  of  refractory  brick ;  and  as  an  insulating  medium  both  in  heat- 
ing and  refrigeration.  It  is  a  first-class  nonconductor  of  heat,  where 
high  temperatures  are  employed,  such  as  around  steel  and  gas  plants 
and  power  houses.  In  such  cases,  it  is  built  in  as  an  insulating  layer 
in  furnace  walls.  In  Germany,  under  the  name  '  kieselguhr, '  it  was 
used  as  an  absorbent  for  nitroglycerine  in  the  early  manufacture  of 
dynamite. 

As  a  nonconductor  of  heat  it  has  been  used  alone  or  with  other  mate- 
rials as  a  covering  for  boilers,  steam  pipes  and  safes,  and  in  fireproof 
cement.  It  is  used  largely  by  paint  manufacturers  as  a  wood  filler. 
Boiled  with  shellac  it  is  made  into  records  for  talking  machines.  It  has 
been  used  for  absorbing  liquid  manures  so  that  they  could  be  utilized 
as  fertilizers,  and  as  a  source  of  silica  in  making  water-glass  as  well  as 
in  the  manufacture  of  cement,  tile  glazing,  artificial  stone,  ultramarine 
and  other  pigments  of  aniline  and  alizarine  colors,  paper  filling,  sealing 
wax,  fireworks,  hard-rubber  objects,  matches,  and  paper  mache,  and

for  solidifying  bromine.  For  making  insulating  brick  the  material  is 
sawed  into  blocks,  and  for  all  other  purposes  it  is  ground  and  screened. 
The  most  important  deposits  in  California  thus  far  known  are  located 
in  Monterey,  Orange,  San  Luis  Obispo,  and  Santa  Barbara  counties. 
The  Santa  Barbara  material  is  diatomaceous  and  is  of  a  superior 
quality,  particularly  for  filtration  uses  which  bring  the  higher  prices. 
Infusorial  or  diatomaceous  earths  are  also  found  in  Fresno,  Kern, 
Los  Angeles,  Plumas,  San  Benito,  San  Bernardino,  San  Joaquin, 
Shasta,  Sonoma,  and  Tehama  counties. 

As  almost  90%  of  the  output  in  California  is  from  a  single  operator, 
we  have  concealed  the  exact  figures  under  the  'Unapportioned'  item 
in  the  state  and  county  totals.  There  were  six  operators  in  1927  in 
Los  Angeles,  Monterey,  Santa  Barbara  and  Shasta  counties,  the  ship- 
ments showing  a  decrease  in  tonnage  and  value  compared  with  1926, 

The  material  shipped  was  utilized  for  insulation,  filtration,  paint 
pigment,  cement  admixture,  and  for  clarification  of  gasoline  and 
kerosene.

DOLOMITE 

Bibliography:  Reports  XV,  XVII-XXII  (inc.).    Bulletins  67,  91. 

The  production  of  dolomite  for  the  year  1927  totaled  45,976  tons 
valued  at  $79,422,  being  decreases  in  both  quantity  and  value  from 
the  1926  figures  of  68,640  tons  and  $119,313.  The  1927  output  came 
from  a  single  quarry  each  in  Inyo  and  Monterey  counties.  The 
material  shipped  was  utilized  for  steel  furnace  flux  and  refractories, 
and  for  manufacture  of  COj.  Some  previously  has  been  used  for 
burned  dolomitic  lime,  for  stucco  dash-coat,  and  terrazzo.

Previous  to  the  1915  statistical  report  of  the  State  Mining  Bureau, 
dolomite  was  included  under  limestone,  as  the  two  minerals  are  closely 
related  chemically;  but  since  dolomite,  as  such,  has  been  found  to  have 
certain  distinctive  applications,  we  here  give  it  a  separate  classification.

FELDSPAR 

BiUiography:  State  Mineralogist  Reports  XV,  XVII,  XVIII, 
XXI.  Bulletins  67,  91.  U.  S.  Bureau  of  Mines,  Bulletin  92. 
Eng.  &  Min.  Jour.-Press,  Vol.  115,  pp.  535-538,  Mar.  24,  1923. 

Feldspar  was  produced  by  four  operators  in  three  counties  (Kern, 
Riverside  and  San  Diego)  during  1927,  to  the  amount  of  10,932  tons, 
valued  at  $86,101,  being  a  slight  increase  both  in  quantity  and  value 
over  the  1926  figures,  which  were  7300  tons  and  $56,400. 

The  requirements  of  the  pottery  trade  demand  that  in  general  the 
percentage  of  free  silica  associated  with  the  feldspar  be  less  than  20%, 
and  in  some  cases  the  potters  specify  less  than  5%.  An  important 
factor,  also,  is  the  iron-bearing  minerals  frequently  present  in  pegma- 
tites and  granites,  such  as  biotite  (black  mica),  garnet,  hornblende,  and 
black  tourmaline.  Feldspar  for  pottery  uses  should  be  practically  free 
of  these.  The  white,  potash-mica,  muscovite,  is  not  particularly  objec- 
tionable except  that,  being  in  thin,  flexible  plates,  it  does  not  readily 
grind  to  a  fineness  required  for  the  feldspar. 

Present  quotations  are  from  $5  to  $9  per  ton,  crude,  according  to 
quality. 

The  most  important  developments  quantitatively  in  the  feldspar 
resources  of  California  have  thus  far  taken  place  in  San  Diego  and 
Riverside  counties,  where  large  deposits  of  massive,  high-grade  spar 
are  being  opened  up.  These  deposits  are  unusually  free  from  black 
mica  and  other  deleterious  iron-bearing  minerals  objectionable  in  pot- 
tery work.  The  important  producing  districts  are  near  Lakeside  and 
Campo,  in  San  Diego  County,  and  near  Lakeview,  Murrietta,  and  Elsi- 
nore,  in  Riverside  County.     Other  deposits  which  give  promise  are

Fluorspar,  or  calcium  fluoride,  CaF^,  is  one  of  the  most  important 
non-metallic  minerals  from  an  industrial  standpoint.  About  80%  of 
the  commercial  mineral  is  prepared  in  the  'gravel'  form  and  utilized 
as  a  flux  in  the  manufacture  of  steel,  for  which  use  no  substitute  has 
yet  been  found.  In  the  United  States,  under  normal  business  condi- 
tions, the  consumption  for  that  purpose  is  125,000  to  150,000  tons 
annually.  Fluorspar  is  also  used  in  aluminum  smelting,  and  in  the 
manufacturing  of  enameled  wiare,  glazed  tile  and  brick,  opalescent  glass 
and  certain  chemicals,  particularly  hydrofluoric  acid  and  its  deriva- 
tives. The  mineral  is  marketed  in  three  forms :  lump,  gravel,  and 
ground. 

According  to  the  U.  S.  Bureau  of  Foreign  and  Domestic  Commerce, 
imports  of  fluorspar  into  the  United  States  in  1926  amounted  to  67,563 
long  tons,  valued  at  $747,237,  and  came  principally  from  England,  with 
smaller  amounts  from  British  South  Africa,  Italy,  China  and  Nether- 
lands. Domestic  shipments  of  fluorspar,  according  to  the  U.  S.  Bureau 
of  Mines,  totaled  128,657  short  tons,  valued  at  $2,341,277. 

In  California  deposits  have  been  reported  in  Los  Angeles,  Mono, 
Riverside  and  San  Bernardino  counties,  but  no  commercial  production 
has  resulted  except  in  1917-1918,  when  a  total  of  79  tons  valued  at  $991 
was  shipped  from  Riverside  County. 

The  Tariff  Act  of  1922  places  a  duty  of  $5.60  per  ton  on  foreign 
importations  of  fluorspar.

FULLER'S  EARTH 

Bibliography:  State  Mineralogist  Reports  XIV,  XVII,  XVIII, 
XXI.  Bulletins  38,  91.  U.  S.  Bureau  of  Mines,  Bulletin  71. 
Eng.  &  Min.  Jour.-Press,  Vol.  121,  pp.  837-842,  May  22,  1926. 

Fuller''s  earth  includes  many  kinds  of  unctuous  clays.  It  is  usually 
soft,  friable,  earthy,  nonplastic,  white  and  gray  to  dark  green  in  color, 
and  some  varieties  disintegrate  in  water.  In  California,  fuller's  earth 
has  been  used  in  clarifying  both  refined  mineral  and  vegetable  oils, 
and  for  special  chemical  purposes;  although  its  original  use  was  in 
fulling  wool,  as  the  name  indicates.  Production  has  come  mainly  from 
Calaveras  and  Solano  counties,  with  other  deposits  noted  also  in  River- 
side, Fresno,  Inyo  and  Kern  counties. 

Clays  of  the  montmorillonite  and  hallosite  group  ('rock  soap')  are 
being  utilized  by  some  of  the  oil  refineries  in  lieu  of  true  fuller's  earth 
in  the  refining  of  petroleum  products. 

The  production  of  13,018  tons  valued  at  $154,764  here  credited  to 
1927  as  'fuller's  earth'  is  in  reality  colloidal  clay  of  the  montmorillonite 
class  (sold  under  such  local  names  as  'bentonite,'  'otaylite, '  'shoshon- 
ite, '  derived  from  the  locality  where  found).  Because  of  its  being 
utilized  for  clarifying,  filtering,  and  cleanser  purposes,  most  of  it  in 
petroleum  refining,  we  have  placed  it,  for  the  purpose  of  the  State 
Division  of  Mines  and  Mining  statistical  reports,  under  the  fuller's 
earth  heading. 

After  all,  the  practical  test  of  a  fuller's  earth  is  not  so  much  chemical, 
as  a  physical  one ;  that  is,  its  physical  capacity  to  absorb  basic  colors 
and  to  remove  these  colors  from  solution  in  animal,  vegetable,  or  min- 
eral oils,  also  from  water. 

The  1927  output  above  noted  is  a  decrease  in  both  amount  and  value 
from  the  23,552  tons  and  $250,192  in  1926,  and  came  from  five  prop- 
erties, in  Inyo,  Kern,  San  Bernardino,  and  San  Diego  counties.

The  production  of  gem  materials  in  California  has  been  somewhat 
irregular  and  uncertain  since  1911.  The  compilation  of  complete 
statistics  is  difficult  owing  to  the  widely  scattered  places  at  which  stones 
are  gathered  and  marketed  for  the  most  part  in  a  small  way.  The 
material  reported  in  1927  totaled  $7,035  in  value,  compared  with 
$9,049  in  1926,  the  decrease  being  due  mainly  to  San  Diego  County. 

The  following  table  shows  the  distribution  of  rough,  uncut  gem  and 
jeweler's  materials  during  1927:

Varieties  of  California's  Gem  Stones. 

Diamonds  have  been  found  in  a  number  of  localities  in  California; 
but  in  every  case,  they  have  been  obtained  in  stream  gravels  while 
working  them  for  gold.  The  principal  districts  have  been :  Volcano  in 
Amador  County;  Placerville,  Smith's  Flat  and  others  in  El  Dorado 
County ;  French  Corral,  Nevada  County ;  Cherokee  Flat,  Morris  Ravine, 
and  Yankee  Hill,  Butte  County ;  Gopher  Hill  and  upper  Spanish  Creek, 
Plumas  County.  The  most  productive  district  of  recent  years  has  been 
Cherokee  in  Butte  County. 

California  tourmalines  are  decidedly  distinctive  in  coloring  and  'fire' 
as  compared  to  foreign  stones  of  this  classification.  The  colors  range 
from  deep  ruby  to  pink,  and  various  shades  of  green,  also  blue. 

One  of  our  California  gem  stones,  henitoite,  has  not  been  found  else-' 
where ;  and  in  but  a  single  locality  here :  The  Dallas  Mine  in  San  Benito 
County, 

Kunzite,  a  gem  variety  of  spodumene,  was  first  found  in  the  Pala 
district  in  San  Diego  County.  It  has  thus  far  been  found  in  only  one 
locality  (Madagascar)  outside  of  California.  It  is  of  a  lilac  color,  and 
is  described  in  detail  in  Bulletin  37  of  the  State  Mining  Bureau. 

Beryls  of  excellent  fire  and  delicate  colors  are  also  obtained  in  the 
Pala  district,  of  which  the  aquamarine  (blue)  and  morganite  (pink) 
varieties  deserve  special  mention.  Morganite,  like  kunzite,  has  thus  far 
been  found  elsewhere  only  in  Madagascar. 

Californite,  or  'California  jade,'  is  a  gem  variety  of  vesuvianite,  and 
is  green  or  white  in  color.  It  is  found  in  Butte,  Fresno,  and  Siskiyou 
counties.

Stones  of  precious  blue  topaz  of  fine  quality  are  being  cut  from  crys- 
tals mined  in  northern  San  Diego  County.  They  are  associated  with 
beryl  and  blue  tourmaline. 

Some  rhodonite  has  been  mined  in  Siskiyou  County,  and  used  for 
decorative  purposes,  its  value  being  included  in  the  marble  figures. 

Garnets  are  found  in  a  number  of  localities  in  California;  the  im- 
portant yield  of  gems  being  hyacinth  and  spessartite  varieties  from  San 
Diego  County. 

Chrysoprase  has  been  produced  in  Tulare  County. 

Turquoise  has  been  found  in  the  desert  section  of  San  Bernardino 
County,  but  none  produced  commercially  in  recent  years. 

Sapphires  have  been  reported  found  in  San  Bernardino  and  Kiver- 
.side  counties,  but  not  as  yet  confirmed.  A  few  have  been  found  in 
stream  gravels  with  diamonds  in  Butte  County. 

Rubies  have  been  identified  by  the  laboratory  of  the  State  Mining 
Bureau,  occurring  in  limestone  from  the  Baldy  Mountains,  San  Bernar- 
dino County.  Thus  far  no  stones  of  commercial  size  have  been 
taken  out.

Graphite  (also  called  plumbago)  has  been  produced  from  time  to  time 
in  the  state,  coming  principally  from  Sonoma  and  Los  Angeles  counties. 
It  is  difficult  for  these  deposits,  which  must  be  concentrated,  to  compete 
with  foreign  supplies,  which  go  on  the  market  almost  directly  as  they 
come  from  the  deposit.  Graphite  ores  are  concentrated  with  consider- 
able difficulty,  and  the  electric  process  of  manufacturing  artificial 
graphite  from  coal  has  been  perfected  to  such  a  degree  that  only 
deposits  of  natural  graphite  of  a  superior  quality  can  be  exploited  with 
any  certainty  of  success. 


102  MINERAL  INDUSTRY  OF  CALIFORNIA 

According  to  the  U.  S.  Geological  Survey,  operators  in  this  country 
who  are  working  disseminated  flake  deposits  must  depend  on  their  No.  1 
and  No.  2  flake  for  their  profit.  Graphite  dust  is  merely  a  by-product 
and  is  salable  only  at  a  low  price. 

The  principal  value  of  graphite  is  on  account  of  its  infusibility  and 
resistance  to  the  action  of  molten  metals.  It  is  also  largely  used  in  the 
manufacture  of  electrical  appliances,  of  'lead'  pencils,  as  a  lubricant, 
as  stove  polish,  paints,  and  in  many  other  ways.  Amorphous  graphite, 
commonly  carrying  many  impurities,  brings  a  much  lower  price.  For 
some  purposes,  such  as  foundry  facings,  etc.,  the  low-grade  material  is 
satisfactory.  Among  the  interesting  uses  for  graphite  is  the  prevention 
of  formation  of  scale  in  boilers.  The  action  is  a  mechanical  one.  Being 
soft  and  slippery,  the  graphite  prevents  the  particles  of  scale  from 
adhering  to  one  another  or  to  the  boiler  and  they  are  thus  easily 
removed. 

The  price  increases  with  the  grade  of  material,  the  best  quality 
crystalline  variety  being  quoted  at  present  (f.o.b.  New  York)  at  7|^-8^ 
per  pound  (Ceylon  lumps). 

The  coarser  flakes  are  necessary  for  crucibles,  as  they  help  to  bind 
the  clay  together  in  addition  to  their  refractory  service.  Imports  in 
1927  from  Ceylon,  Canada,  Madagascar,  Mexico  and  Korea,  totaled 
17,429  short  tons  valued  at  $722,004  compared  with  16,194  tons  valued 
at  $923,513  in  1926. 

Occurrence  of  graphite  has  been  reported  at  various  times  from  Cala- 
veras, Fresno,  Imperial,  Inyo,  Los  Angeles,  Mendocino,  San  Bernardino, 
San  Diego,  Siskiyou,  Sonoma  and  Tuolumne  counties. 

During  1927  there  was  a  small  commercial  output  of  graphite  from 
Los  Angeles  County.  For  several  years  a  single  plant  in  Los  Angeles 
County  has  been  concentrating  graphite  from  a  disseminated  ore,  the 
product  being  used  for  paint  and  for  foundry  facing.

GYPSUM 

Bibliography:  State  Mineralogist  Reports  XIV,  XV,  XVII,  XVIII, 
XXII.  Bulletins  38,  67,  91.  U.  S.  Geol.  Surv.,  Bull.  223,  413, 
430,  697.    U.  S.  Bur.  of  Standards,  Circular  No.  281. 

During  1927  one  operator  each  in  Imperial  and  Kern  counties  and 
two  in  Riverside  produced  a  total  of  94,630  tons  of  gypsum,  valued  at 
$292,090,  compared  with  114,868  tons  and  $211,337  in  1926.  The 
material  was  utilized  mainly  in  cement  manufacture  as  a  retardant,  for 
hard-wall  plaster  (including  wall  board),  and  for  fertilizer. 

Uses. 

The  most  important  use  of  gypsum  from  the  quantity  standpoint  is 
in  the  calcined  form  where  it  is  utilized  in  the  manufacture  of  various 
liard-wall  plasters  and  plaster  board.  As  plaster  of  paris,  it  plays  a 
very  important  part  in  surgical  work.  Approximately  2%,  by  weight, 
raw  gypsum  is  added  in  the  manufacture  of  Portland  cement  just 
before  the  final  grinding.  In  this  application,  the  gypsum  acts  as  a 
retarder  to  the  set  of  the  cement.  The  use  of  gypsum  tile  for  non- 
bearing  fireproof  partitions,  stairway  and  elevator  enclosures,  and  the 
protection  of  steel  columns,  girders  and  beams,  has  increased  greatly. 

Keene's  cement  is  a  gj^psum  product,  calcined  to  complete  dehydra- 
tion, and  an  accelerator  added  such  as  alum,  potassium  sulphate,  borax, 
aluminum  sulphate. 

Land  plaster  may  be  applied  to  the  soil  by  drilling,  or  scattered  in 
the  hill,  or  it  may  be  sowed  broadcast,  in  quantities  ranging  from  200 
to  500  pounds  to  the  acre. 


Total  Production  of  Gypsum  in  California. 

Production  of  gypsum  annually  in  California  since  such  records  have 
been  compiled  by  this  Bureau  is  as  follows :

'Industrial'  limestone  was  produced  in  nine  counties  during  1927, 
to  tlie  amount  of  699,790  tons,  valued  at  $663,957,  being  an  increase 
both  in  quantity  and  value  compared  to  the  1926  output  of  108,795 
tons,  worth  $367,501. 

The  amount  here  given  does  not  include  the  limestone  used  in  the 
manufacture  of  cement  nor  for  macadam  and  concrete,  nor  of  lime  for 
building  purposes;  but  accounts  for  that  utilized  as  a  smelter  and 
foundry  flux,  for  glass  and  sugar  making,  and  other  special  chemical 
and  manufacturing  processes.  It  also  includes  that  utilized  for  fer- 
tilizers (agricultural  'lime'),  'roofing  gravel,'  paint  and  concrete  filler, 
whiting  for  paint,  putty,  kalsomine,  terrazzo,  paving  dust,  chicken  grit, 
carbon  dioxide  gas,  'paving  compound,'  facing  dust  for  concrete  pipe, 
also  for  rubber  and  magnesite  mix.  That  from  Santa  Clara  and  Los 
Angeles  counties  is  calcareous  marl  sold  for  agricultural  purposes. 
Of  the  total  product  in  1927,  approximately  23,183  tons,  valued  at 
$41,096,  were  used  for  agricultural  purposes. 

Distribution  of  the  1927  output  was  as  follows :

Limestone  Production  of  California,  by  Years. 

The  following  tabulation  gives  the  amounts  and  value  of  'industrial' 
limestone  produced  in  California  by  years  since  1894  when  compilation 
of  such  records  was  begun  by  the  State  Mining  Bureau.  These  ton- 
nages consist  principally  of  limestone  utilized  for  flux,  glass  and  sugar 
making,  agricultural,  chemical,  and  other  special  industrial  purposes. 
That  utilized  in  cement  manufacture  is  not  included.

Lithia  mica,  lepidolite  (a  silicate  of  lithium  et  al.)  utilized  in  the 
manufacture  of  artificial  mineral  water,  fireworks,  glass,  etc.,  has  been 
mined  in  San  Diego  County  since  1899,  except  between  1905  and  1915, 
though  there  was  none  shipped  in  1923  and  1925.  The  1927  figures 
are  concealed  under  the  'Unapportioned'  item.  Some  amblygonite,  a

I  '•    Classification   and    Uses. 

Practically  all  marketable  mica  is  of  the  muscovite  or  phlogopite 
varieties.  There  are  three  main  commercial  classes :  Sheet  mica,  includ- 
ing punch;  splittings,  and  scrap.  Sheet  mica  is  used  chiefly  for 
electrical  purposes  and  for  glazing;  splittings  are  made  into  built-up 
mica ;  scrap  is  ground  to  a  powder.  Mica  to  be  classified  as  sheet  must 
yield  a  rectangle  of  at  least  1|  x  2  in.,  must  split  evenly  and  freely, 
be  free  from  cracks,  rulings,  or  plications,  and  reasonably  free  from 
inclusions  of  foreign  matter,  though  stains  of  a  nonconducting  character 
are  permissible  for  some  uses.  Ability  to  withstand  heat  and  high 
electrical  resistance  have  led  to  a  wide  application  of  sheet  mica  in 
the  electrical  industries.  The  electrical  uses  of  sheet  mica  greatly 
exceed  all  others  in  quantity  and  value  of  the  material  used. 

As  a  heat-resisting  transparent  medium,  sheet  mica  has  various  uses. 
It  is  widely  employed  for  stove  windows,  though  this  use  has  declined 


106 


MINERAL    INDUSTRY    OF    CALIFORNIA 


to  a  considerable  extent.  A  hard  and  rigid  mica  that  is  nearly  clear 
is  best  suited  for  stove  fronts.  High-grade  stove  mica  commands  a 
higher  price  than  electrical  mica,  because  for  the  most  part  larger 
sizes  are  demanded.  Mica  is  also  used  in  furnace  and  bake-oven  sight- 
holes,  heat  screens,  lamp  chimneys,  canopies  and  shades,  particularly 
for  gas  mantles,  and  also  for  military  lanterns  and  in  lantern  slides. 

Its  ability  to  withstand  shocks  and  strains,  combined  with  its  trans- 
parency, has  led  to  wide  use  in  motor  goggles,  spectacles,  divers' 
helmets,  smoke  helmets,  compass  cards,  gage  fronts,  and  in  windows 
subject  to  shock,  as  in  the  conning  towers  of  warships.  On  account 
of  its  heat-resisting  qualities,  ground  mica  is  used  in  railroad  car  axle 
packings,  in  pipe  and  boiler  coverings,  in  fire-proof  paints,  and  in 
rubber  tires.  Ground  mica  is  used  as  a  component  in  roofing,  as  a 
filler  in  rubber  and  other  products,  in  calico  printing,  and  as  a  tire 
powder.  It  is  used  also  in  tinsel  decorations,  and  as  '  Santa  Claus  snow ' 
for  Christmas  tree  and  window  decorations.  It  is  used  as  a  lubricant 
for  wooden  bearings,  and  mixed  with  oil  for  metal  bearings. 

MINERAL  PAINT

Mineral  paint  material  was  produced  in  California  in  1927  by  a 
single  operator  in  Stanislaus  County.  This  material  was  a  yellow 
ochre.  Tliere  was  a  slight  decline  in  both  quantity  and  value  from  the 
1926  production. 


Mineral  Paint  Production  of  California,  by  Years. 

The  first  recorded  production  of  mineral  paint  materials  in  the  state 
was  in  the  year  1890.  The  output,  showing  annual  amount  and  value 
since  that  time,  is  given  herewith :

STATISTICS   OF   ANNUAL   PRODUCTION  107 

MINERAL  WATER. 

Bibliography :  State  Mineralogist  Reports  VI,  XII-XVIII  (inc.), 
XXI-XXIII  (inc.).  U.  S.  G.  S.,  Water  Supply  Paper  338.  Min. 
Res.  1914,  1916.  'Mineral  Springs  and  Health  Resorts  of  Cali- 
fornia,' by  Dr.  Winslow  Anderson,  1890.  U.  S.  Dept.  of  Agr., 
Bur.  of  Chem.,  Bulletin  91. 

A  widespread  production  of  mineral  water  is  shown  annually  in 
California.  These  figures  refer  to  mineral  water  actually  bottled  for 
sale,  or  for  local  consumption.  Water  from  some  of  the  springs  having 
a  special  medicinal  value  brings  a  price  many  times  higher  than  the 
average  shown,  while  in  some  cases  the  water  is  used  merely  for  drink- 
ing purposes  and  sells  for  a  nominal  figure.  Health  and  pleasure 
resorts  are  located  at  many  of  the  springs.  The  waters  of  some  of  the 
hot  springs  are  not  suitable  for  drinking,  but  are  very  efficacious  for 
bathing. 

From  a  therapeutic  standpoint,  California  is  particularly  rich  in 
jmineral  springs.  The  counterparts  of  many  of  the  world-famed  spas 
[of  Europe  and  the  eastern  United  States  can  be  found  here.  Radio- 
[activity  has  been  noted  in  at  least  three  localities  in  California :  At  The 
[Geysers  in  Sonoma  County,  Arrowhead  Hot  Springs  in  San  Bernardino 
[County,  and  Paraiso  Springs,  Monterey  County.  It  doubtless  exists 
[at  others,  but  the  State  Division  of  Mines  and  Mining  has  not  as  yet 
[had  funds  available  to  conduct  the  necessarj^  investigations  along  this 
lline. 

So  far  as  the  efficacy  of  radioactivity  in  mineral  water  is  concerned, 
"it  has  been  found  by  investigations  of  the  U.  S.  Geological  Survey 
and  the  U.  S.  Department  of  Agriculture  that  it  is  not  retained  and 
transported  in  bottled  water.  Radioactivity  in  water  is  only  tempo- 
rary, and  dissipates.  To  obtain  whatever  therapeutic  effect  it  may 
possess,  radioactive  water  should  be  utilized  directly  at  the  spring. 

Commercial  production  of  mineral  water  in  California  for  1927 
amounted  to  a  total  of  16,644,423  gallons,  valued  at  $1,487,183,  being 
a  new  high  record  in  quantity  and  value  over  all  previous  years.  The 
1927  output  was  distributed  by  counties,,  as  follows :

and  a  material  increase  annually  both  in  total  quantity  and  value,  as 
may  be  noted  from  the  tabulation  below. 

Mineral  Water  Production  of  California,  by  Years. 

Mineral  water  was  bottled  for  sale,  at  the  Napa  Soda  Springs,  Napa 
County,  as  early  as  1860,  and  at  other  springs  in  California,  notably 
The  Geysers,  Sonoma  County,  also  at  early  dates;  but  there  are  no

PHOSPHATES 
Bibliography:  State  ]\Iineralogist  Report  XXI.     Bulletins  67,  91. 

No  commercial  production  of  phosphates  has  been  recorded  from 
California,  though  occasional  pockets  of  the  lithium  phosphate,  ambly- 
gonite,  Li  (AlF)  PO4,  have  been  found  associated  with  the  gem  tour- 
maline deposits  in  San  Diggo  County.  Such  production  has  been 
classified  under  lithia. 

PUMICE    and    VOLCANIC    ASH 

Bibliography:  State  Mineralogist  Reports  XII,  XIV,  XV,  XVII, 
XVIII,  XXII.    Bulletin  38  (See  'Tufa'). 

The  production  of  pumice  and  volcanic  ash  for  the  year  1927 
amounted  to  13,779  tons  valued  at  $168,896,  and  came  from  properties 
in  Fresno,  Imperial,  Inyo,  Kern,  Mono,  and  San  Luis  Obispo  counties. 
In  1927  an  increase  both  in  tonnage  and  value  compared  with  the  1926 
shipments,  which  were  7170  tons,  worth  $48,350,  although  the  1927 
figures  include  also  production  over  the  past  four  years  from  a  deposit 
for  which  reports  had  not  been  previously  received. 


STATISTICS   OF   ANNUAL   PRODUCTION 


109 


The  material  from  Imperial  County  and  part  of  that  from  Mono  is 
of  the  vesicular,  block  variety  and  was  sold  for  abrasive  purposes ;  the 
balance  of  the  Mono  material  and  that  from  Fresno,  Inyo,  Kern  and 
San  Luis  Obispo  was  the  volcanic  ash,  or  tuff  variety,  and  was  employed 
in  making  soap,  cleanser  compounds  and  a  large  tonnage  is  being 
utilized  as  a  concrete  filler  in  cement  displacement.  The  Kern  County 
ash  is  going  into  the  preparation  of  one  of  the  popular  and  nationally 
advertised  brands  of  cleanser  compounds.. 

Pumice  Production  of  California,  by  Years. 

Commercial  production  of  pumice  in  California  was  first  reported  to 
the  State  Mining  Bureau  in  1909,  then  not  again  until  1912,  since  which 
year  there  has  been  a  small  annual  output,  as  indicated  by  the  follow-

PYRITES 

Bihliography :  State  Mineralogist  Reports  XVIII,   XIX,   XXII. 
Bulletins  38,  91.    Min.  and  Sci.  Press,  Vol.  114,  pp.  825,  840. 

A  total  production  of  130,910  tons  of  pyrite,  valued  at  $564,823,  was 
reported  shipped  in  California  during  1927,  from  properties  in  Ala- 
meda, Mariposa,  Shasta  and  San  Benito  counties.  This  was  an  increase 
both  in  quantity  and  value  over  100,896  tons,  valued  at  $466,088,  in 
1926.  The  material  from  San  Benito  County  was  an  iron  sulphate  (not 
an  iron  sulphide),  and  that  from  Mariposa  County  contains  both  sul- 
phide and  sulphate,  but  used  for  the  same  purposes  as  some  of  the 
pyrite  and  therefore  classed  as  pyrite. 

The  material  was  mostly  used  in  the  manufacture  of  sulphuric  acid 
for  explosives  and  fertilizers,  but  a  portion  was  utilized  directly  in  the 
preparation  of  agricultural  fertilizer  and  insecticide.  The  sulpliur 
content  ranged  up  to  46.5%  S. 

This  does  not  include  the  large  quantities  of  pyrite,  chalcopyrite,  and 
other  sulphides  which  are  otherwise  treated  for  their  valuable  metal 
contents.  Some  sulphuric  acid  is  annually  made  as  a  by-product  in 
the  course  of  roasting  certain  tonnages  of  Mother  Lode  auriferous 
concentrates  while  under  treatment  for  their  precious  metal  values.

SHALE  OIL

Oil  Shale  is  defined  by  Gavin, ^  as  follows : 

"Oil  shale  is  a  compact,  laminated  rock  of  sedimentary  origin,  yielding  over  33  per 
cent  of  ash  and  containing  organic  matter  that  yields  oil  when  distilled,  but  not 
appreciably  when  extracted  with  the  ordinary  solvents  for  petroleum. 


* 


* 


"Oil  shales  contain  a  substance,  or  substances,  usually  classed  as  a  pyro-bltumen, 
that  l)y  destructive  distillation,  or  pyrolysis,  yields  oils  somewhat  similar  to  petroleum. 
These  substances  have  been  termed  'kerogen,'  from  two  Greek  words  meaning 
producer  of  wax." 

The  Scottish  oil  shales  are  also  known  as  'torbanite. ' 
The  so-called  'oil  shales'  of  California  do  not  for  the  most  part  con- 
form to  the  above  definition,  as  the  greater  part  of  the  oil  obtained  from 
them  occurs  as  such  and  can  be  extracted  by  suitable  solvents.  The 
most  extensive  deposits  in  this  state  are  part  of  the  Monterey  formation 
of  Tertiary  age,  and  phj^sically  and  chemically  are  dififerent  from  the 
oil  shales  of  Scotland  and  from  other  oil  shales  in  the  United  States. 
The  mineral  matter  of  this  shale  is  diatomaceous ;  the  beds  that  yield 
oil  occur  in  massive  formation ;  and  when  freshly  broken  smell  strongly 
of  petroleum.  Most  geologists  consider  the  Monterey  shales  to  have 
been  the  origin  of  the  oil  in  some  of  the  oil  fields  of  California. 

Although  the  extraction  of  shale  oil  has  been  a  matter  of  commercial 
practice  on  a  considerable  scale  for  many  years  in  Scotland,  France, 
and  Australia,  it  has  not  attained  any  great  commercial  importance 
as  5^et  in  the  United  States.  Technical  knowledge  of  the  subject,  how- 
ever, is  increasing.  With  the  gradual  depletion  of  the  underground 
reserves  of  liquid  oil,  it  is  merely  a  matter  of  time  until  the  develop- 
ment of  the  oil  shales  of  the  United  States  will  be  an  economic  necessity.

STATISTICS   OF    ANNUAL   PRODUCTION  111 

The  selling  price  of  petroleum  will  be  the  determining  factor.  The 
recovery  of  by-product  ammonium  sulphate  is  an  important  feature  of 
the  process. 

Two  plants  on  a  more  or  less  experimental  scale  have  been  in  opera- 
tion in  California  for  several  years  past,  with  commercial  production 
beginning  in  a  small  way  in  1922.  The  product,  in  part,  has  been  sold 
for  utilization  as  a  flotation  oil  in  metallurgical  work,  and  part  has 
been  consumed  as  fuel  at  the  plants.  As  only  one  plant  reported  output 
for  1927,  the  value  is  concealed  under  the  'unapportioned'  item.

SILICA   (Sand  and   Quartz) 

Bibliography:  State  Mineralogist  Reports  IX,  XIV,  XV,  XVII, 
XVIII,  XX-XXIII.    Bulletins  38,  67,  91. 

We  combine  these  materials  because  of  the  overlapping  roles  of  vein 
quartz  which  is  mined  for  use  in  glass  making  and  as  an  abrasive,  and 
that  of  silica  sand  which,  although  mainly  utilized  in  glass  manufac- 
ture, also  serves  as  an  abrasive.  Both  varieties  are  also  utilized  to 
some  extent  in  fire-brick  manufacture. 

A  portion  of  the  tonnage  of  vein  quartz  in  California  in  1916  and 
1917  was  employed  in  the  preparation  of  ferro-silicon  by  the  electric 
furnace.    At  present,  some  is  utilized  as  a  foundry  flux,  and  for  steel- 
casting  molds.    A  portion  of  the  silica  sold  (both  sand  and  quartz)  is 
also  used  in  glazes  for  porcelain,  pottery  and  tile,  and  in  the  body  of 
the  ware  to  diminish  shrinkage ;  and  some  of  the  sand  for  the  prepara- 
tion of  sodium  silicate   ('water  glass').     Manufacturers  of  paint  use 
finely  ground  silica,  which  forms  as  much  as  one-third  of  the  total 
pigment  in  some  paints.     For  certain  purposes  finely-ground  crystalline 
material  is  superior  in  paints  to  other  materials  because  of  the  angu- 
larity of  the  grains,  which  makes  them  adhere  more  firmly  to  the  article 
,  painted  and  after  wear  afford  a  good  surface  for  repainting.     The 
i  same    angularity    makes    artificially    comminuted    crystalline    quartz 
;  superior  to  natural  sand  for  use  in  wood  fillers.     It  is  also  preferable 
i  for  soaps  and  polishing  powders.    Part  of  the  1925  output  was  used  for 
'  roofing  and  stucco-dash  granules. 

I  We  do  not  include  under  this  heading  such  forms  of  silica  as: 
i  quartzite,  sandstone,  flint,  tripoli,  diatomaceous  earth,  nor  the  gem 
i  forms  of  'rock  crystal,'  amethyst,  and  opal.  Each  of  these  has  various 
i  industrial  uses,  which  are  treated  under  their  own  designations. 

The  production  of  silica  in  California  in  1927  amounted  to  24,636 

tons,  valued  at  $94,762,  from  nine  properties  in  five  counties.    This  was 

a  decrease  from  30,010  tons  valued  at  $104,317  in  1926. 

,    Of  the  above  total  11,150  tons  was  of  sand  and  13,486  tons  of  vein 

land  boulder  quartz.    For  making  the  higher  grades  of  glass,  most  of 


112 


MINERAL    INDUSTRY    OF    CALIFORNIA 


the  sand  is  imported  from  Belgium.  Belgian  sand  has  also  displaced 
local  material  in  the  manufacture  of  sodium  silicate  ('water-glass'). 
There  are  various  deposits  of  quartz  in  California  which  could  be 
utilized  for  glass  making,  but  to  date  they  have  not  been  so  used  owing 
to  the  cost  of  grinding  and  the  difficulty  of  preventing  contamination 
by  iron  while  grinding. 

Silica  sand  has  been  produced  in  the  following  counties  of  the  state  .- 
Alameda,  Amador,  El  Dorado,  Los  Angeles,  Mono,  Monterey,  Orange, 
Placer,  Riverside,  San  Diego,  San  Joaquin,  and  Tulare,  the  chief  centers 
being  Amador,  Monterey  and  Los  Angeles  counties.  The  industry  is 
of  limited  importance,  so  far,  because  of  the  fact  that  much  of  the 
available  material  is  not  of  a  grade  which  will  produce  first-class 
colorless  glass ;  for  such,  it  must  be  essentially  iron-free.  Even  a  frac- 
tional per  cent  of  iron  imparts  a  green  color  to  the  glass.

SILLIMANITE— ANDALUSITE— CYANITE  GROUP 

Bibliography:  State  Mineralogist  Report  XX.  Bulletins  67,  91. 
Dana's  Mineralogy.  U.  S.  Geol.  Surv.,  Prof.  Paper  110.  Eng. 
&  Min.  Jour.-Press,  Vol.  120,  pp.  91-94,  1925.  Amer.  Mineral- 
ogist, June,  1924. 

Sillimanite  and  andalusite  are  both  aluminum  silicates  (AloSiOg), 
having  the  same  composition  and  formula,  but  with  slightly  different 
physical  characteristics.  Though  both  crystallize  in  the  orthorhombic 
system,  their  crystal  habits  are  different,  andalusite  being  usually  in 
coarse  prismatic  forms,  the  prisms  nearly  square  in  shape;  also  occurs 
massive,  imperfectly  columnar,  and  sometimes  radiated  and  granular. 
Sillimanite  commonly  occurs  in  long,  slender  crystals,  not  distinctly 
terminated;  prismatic  faces  striated  and  rounded;  often  in  close 
parallel  groups,  passing  into  fibrous  and  columnar  massive  forms, 
sometimes  radiating.  Colors  are  similar.  Hardness,  andalusite  7.5, 
sillimanite  6-7.    Andalusite  is  slightly  lighter  in  specific  gravity. 

A  massive  deposite  of  andalusite,  found  in  Dry  Creek  Canyon  in  the 
White  Mountains  of  the  Inyo  Range,  in  Mono  County,  is  being  mined 
by   the   Champion  Porcelain   Company   of   Detroit,   Michigan.     The 


STATISTICS   OF    ANNUAL   PRODUCTION  113 

material  is  shipped  East  and  utilized  in  the  manufacture  of  porcelain 
for  automobile  spark  plugs,  for  other  high-tension  electric  insulators, 
laboratory  ware  and  porcelain.  Porcelain  made  from  these  minerals 
can  be  subjected  to  sudden  and  extreme  changes  in  temperature  with- 
out damage. 

Cyanite  is  also  an  aluminum  silicate  (ALSiOg),  of  the  same  chemical 
composition  as  andalusite  and  sillimanite,  but  crystallizing  in  the 
triclinic  system.  Occurs  usually  in  long-bladed  crystals,  rarelj^  termi- 
nated; hardness  5-7.25;  gravity  3.56-3.67  (being  heavier  than  the  other 
two)  ;  color,  blue.  A  deposit  of  cyanite,  apparently  in  quantity,  is 
being  developed  in  Imperial  County,  near  Ogilby,  and  shipments  made 
to  a  refractory  plant  in  Los  Angeles. 

Dumortierite,  though  differing  somewhat  in  composition  from  the 
above,  being  a  basic  aluminum  silicate  (4  AUOg.S  SiOa),  has  proved 
similar  in  behavior  in  ceramic  work  so  that  it  is  now  being  mixed  with 
andalusite  for  electrical  porcelains.  A  deposit  of  this  mineral  in 
Nevada  is  being  mined  for  that  purpose.  Occurrences  of  massive 
dumortierite  are  known  in  Imperial  County  in  this  state  and  there  may 
yet  be  some  commercial  possibilities  for  them.

to  16,218  tons,  valued  at  $164,744,  compared  with  17,004  tons,  valued 
at  $255,645  in  1926.  Nearly  80  per  cent  of  the  product  was  high-grade 
talc  from  Inyo,  San  Bernardino  and  Shasta  counties,  which  material 
was  utilized  mainly  in  toilet  powders,  paint,  paper,  and  rubber  manu- 
facture, and  some  in  ceramics,  the  remaining  coming  from  a  single 
producer  each  in  Butte,  Calaveras  and  El  Dorado  counties. 
'  The  'soapstone'  grades  were  used  mainly  for  roofing  granules  and  as 
a  filler  in  roofing  paper,  and  part  also  in  mag-nesite  cement. 

It  is  reported  that  California  talc  is  steadily  replacing  imported  talc 
in  the  toilet  trade  on  the  basis  of  quality.  The  largest  production  of 
jtalc  in  the  United  States  comes  from  Vermont  and  New  York,  and  of 
tmassive  soapstone  from  Virginia. 

Composition  and   Varieties. 

Talc   is    hydrous    magnesium    silicate    with    the    chemical    formula 

'3,Mg3(Si03)4.     It  is  also  called  soapstone  and  steatite.     The  term 

talc'  properly  includes  all  forms  of  the  pure  mineral,  whereas  'steatite' 

i  8 — G2279 

I 


114  MINERAL  INDUSTRY  OF  CALIFORNIA 

denotes  particularly  the  massive,  compact  variety,  and  'soapstone'  the 
impure,  massive  forms  containing  as  low  as  50%  of  talc.  When  pure, 
talc  is  soft,  having  a  hardness  of  1,  but  impurities  increase  the  hardness 
up  to  3  or  4.  The  color  varies  from  pure  white  and  silvery  white 
through  gray,  green,  apple  green,  to  dark  green,  also  yellow,  brown, 
and  reddish  when  imj^ure.  It  is  commonly  compact  or  massive,  or  in 
fine  granular  aggregates,  and  often  in  foliated  plates  or  in  fibrous 
aggregates. 

Uses. 

Although  the  uses  of  talc  and  soapstone  are  many  and  varied,  some 
of  them  are  not  in  general  well  known  nor  fully  developed ;  and 
although  few  of  tlieir  uses  can  justly  be  considered  essential  in  the 
sense  that  no  substitute  can  be  used,  there  are  several  which  are  of 
great  importance.  The  -widest  use  of  talc  is  in  the  powdered  form,  and 
the  value  depends  upon  color  (wliiteness),  uniformity,  fineness  of  grain, 
freedom  from  grit,  'slip,'  and  sometimes  freedom  from  lime.  The  white 
varieties,  free  from  grit  and  iron,  low  in  lime,  ground  to  200-mesh  and 
finer,  are  largely  used  as  a  filler  for  paper,  rubber  and  paint,  and  the 
very  highest  grade  as  toilet  powder.  Ground  talc  is  also  used  in 
dressing  and  coating  cloth,  in  making  soap,  rope,  twine,  pipe-covering 
compounds,  heavy  lubricants,  and  polishes,  and  as  a  filler  in  con- 
crete to  make  it  waterproof.  Ground  talc  and  soapstone  are 
used  for  foundry  facings,  either  alone  or  mixed  with  graphite  and 
a  coarser  grade  is  used  in  the  manufacture  of  asphalt-coated  roofing 
felts  and  papers,  both  as  a  filler  and  as  a  surfacing.  Massive  close- 
grained  talc,  free  from  iron  and  grit,  is  cut  into  blanks  and  baked, 
forming  the  material  used  for  gas  tips  and  electrical  insulation,  com- 
monly known  as  'lava.'  Its  hardness,  its  resistance  to  heat,  acids  and 
alkalies,  and  its  great  dielectric  strength  make  it  A^ery  useful  for  electric 
insulation,  and  no  satisfactory  substitute  for  it  has  been  found. 

Massive  varietias  of  talc,  pyrophyllite.  and  high  grades  of  soapstone 
are  cut  into  slate  pencils  and  steel-workers'  crayons.  'French  chalk' 
or  'tailor's  chalk'  is  a  soft,  massive  talc.  In  China,  Japan  and  India, 
massive  tale  (steatite)  is  carved  into  grotesque  images  and  other  forms, 
and  is  often  sold  as  imitation  jade.  Soapstone  is  cut  into  slabs  of  1 
and  2  inches  in  thickness  and  sold  as  griddles,  foot  warmers,  and  fireless- 
cooker  stones,  or  fabricated  into  laundry  sinks  and  tubs,  laboratory- 
table  tops,  hoods,  tanks  and  sinks,  electric  switchboards,  and  for  other 
uses  in  which  the  properties  of  resistance  to  heat,  acids  and  alkalies, 
and  electricity  are  essential.  *, 


Imports.  I 

Foreign  importations  of  high-grade  white  talc  suitable  for  the  manu- 
facture of  toilet  powder  have  come  mainly  from  Canada,  Italy  and 
France.  Foreign  producers  have  the  benefit  of  cheap  labor,  and  a  low 
tariff  import  duty.  In  addition  to  these  disadvantages,  California 
operators  have  to  contend  with  transcontinental  freight  rates  to  the 
eastern  manufacturing  centers.  In  1927  importations  totaled  25,123 
short  tons,  valued  at  $545,285,  compared  with  24,346  tons,  valued  at 
$563,799  in  1926,  according  to  the  United  States  Bureau  of  Foreign 
and  Domestic  Commerce.

STRONTIUM 


BiUiography :  Bulletins  67,  91.    U.  S.  G.  S.,  Bull.  540;  660-1. 


There  has  been  no  production  of  strontium  minerals  in  California 
since  1918,  though  in  that  year  both  celestite  (SrSO^),  and  the  car- 
bonate, strontianite  (SrCO,,)  were  shipped.  The  first  recorded  com- 
mercial output  of  strontium  minerals  in  California  was  in  1916.  The 
occurrence  of  the  carbonate  is  particularly  interesting  and  valuable,  as 
it  appears  to  be  the  only  considerable  deposit  of  commercial  importance 
so  far  opened  up  in  the  United  States.  Shipments  reported  as  averag- 
ing 80%  SrCOg  have  been  made.  The  deposit  is  associated  with  deposits 
of  barite,  near  Barstow,  San  Bernardino  County.  The  carbonate  has 
also  been  found  in  massive  form  near  Shoshone,  Inyo  County.  In  addi- 
tion to  Imperial  County,  celestite  is  found  near  Calico  and  Ludlow, 
and  in  the  Avawatz  Mountains  in  San  Bernardino  County,  but  as  yet 
undeveloped. 

Production  of  strontium  minerals  in  California,  by  years,  has  been  as

The  principal  use  for  strontium  in  the  United  States  is  in  the  form 
of  the  nitrate  in  the  manufacture  of  red  flares,  or  Costen  and  Bengal 
lights  and  fireworks.  It  is  imported  mainly  from  Germany  and  Eng- 
land. In  Germany  and  Russia,  strontium  in  the  form  of  the  hydroxide 
is  used  in  the  manufacture  of  beet  sugar.  It  is  stated  that  strontia  is 
more  efficient  and  satisfactory  in  that  process  than  lime,  as  it  gives  an 
additional  recovery  of  6%  to  8%. 


116  MINERAL  INDUSTRY  OF  CALIFORNIA 

Of  the  two  minerals,  strontianite  (carbonate)  and  eelestite  (sulphate), 
the  carbonate  is  the  more  desirable  as  it  is  easier  to  convert  to  other 
salts ;  but  it  is  scarcer.  Celestite  is  found  with  limestone  and  sandstone 
and  is  sometimes  associated  with  gypsum.  Strontianite  is  also  found 
with  limestone,  but  associated  with  barite  and  calcite. 

SULPHUR 

Bibliography :  State  Mineralogist  Keports  IV,  XIII,  XIV.    Bulle- 
tins 38,  67,  91. 

In  1923-1924  there  was  a  small  production  of  sulphur,  from  a  single 
property  in  Kern  County.  It  was  ground,  and  utilized  as  a  fertilizer 
and  in  dusting  for  mildew.  This  was  the  first  commercial  output  of 
native  sulphur  in  California  for  many  years  although  this  mineral  has 
been  found  to  some  extent  in  Colusa,  Imperial,  Inyo,  Kern,  Lake, 
Sonoma,  Tehama,  and  Ventura  counties. 

Sulphur  was  produced  at  the  famous  Sulphur  Bank  mine  in  Lake 
County,  during  the  years  1865-1868  (inc.),  totaling  941  tons,  valued  at 
$53,500;  following  which  the  property  became  more  valuable  for  its 
quicksilver.  The  Elgin  quicksilver  mine,  near  Wilbur  Springs,  Colusa 
County,  is  a  similar  occurrence. 

The  principal  sources  in  the  United  States  are  the  stratified  deposits 
in  Louisiana  and  Texas,  extraction  being  accomplished  by  a  unique 
system  of  wells  with  steam  pipes.  It  is  stated  that  three  large  com- 
panies operating  there  are  capable  of  producing  more  than  1,000,000 
tons  annually  in  excess  of  our  normal  consumption  in  the  United 
States,  which  averages  about  600,000  tons.  The  mines  at  Freeport, 
Texas,  are  in  a  jDeculiarly  favorable  location  in  that  they  are  practically 
at  tidewater. 

Formerly  considerable  sulphur  was  imported  from  Italy  and  from 
Japan ;  but  the  situation  is  now  reversed,  so  that  in  1927,  a  total  of 
789,371  long  tons,  valued  at  $16,269,254,  was  exported  from  the  United 
States,  principally  to  Europe  and  Canada,  also  Australia,  New  Zealand, 
Mexico  and  South  America.

Except  for  a  single  year's  absence,  soda  has  had  a  continuous  produc- 
tion since  1894.  Potavsh,  magnesium  chloride  and  sulphate,  and  calcium

1926  joined  by  bromine.    The  nitrates  are  still  prospective.

BORATES 

Bibliography :  State  Mineralogist  Reports  III,  X,  XII-XV  (inc.), 
XVil-XXIII  (inc.).     Bulletins  24,  67,  91. 

During  1927  there  was  produced  in  California  a  total  of  89,093  tons 
of  borate  materials  compared  with  84,101  tons  for  the  year  1926.  The 
material  shipped  during  the  year  included  crude  and  select  colemanite 
ore  from  Inyo  County,  the  new  sodium  borates,  kernite  (Rasorite)  and 
kramerite  from  Kern  County ;  also  crystallized  borax  prepared  by 
evaporation  of  brines  at  Searles  Lake  in  San  Bernardino  County. 

As  the  crude  ore  is  not  sold  as  such,  but  is  almost  entirely  calcined 
before  shipping  to  the  refinery  for  conversion  into  the  borax  of  com- 
merce, and  because  of  the  fact  that  the  material  varied  widely  in  boric 
acid  content,  we  have  recalculated  the  tonnage  to  a  basis  of  40%  A.B.A. 
This  is  approximately  the  average  A.B.A.  content  of  the  colemanite 
material  after  calcining,  and  also  of  the  crystallized  borax  obtained 
from  evaporation  of  the  lake  brines. 

Recalculated  as  above,  the  1927  production  totals  72,462  tons,  valued 
at  $3,043,260,  an  increase  over  the  similar  figures  for  1926,  which  were 
47,605  tons  and  $1,625,298. 


118  MINERAL    INDUSTRY    OF    CALIFORNIA 

Colemanite  is  a  calcium  borate,  and  the  material  mined  is  shipped  to 
seaboard  chemical  plants  for  refining.  The  latest  development  in  the 
borax  industry  is  the  finding  in  quantity  and  opening  up  of  a  new 
borate  mineral  which  bids  fair  to  supplant  colemanite  in  much  the 
same  way  that  the  colemanite  deposits  displaced  the  borax  industry  in 
the  desert  playas  or  dry  lakes,  some  forty  years  ago.  This  new  mineral 
is  'kernite'  (or  'rasorite'),  a  sodium  borate  with  a  smaller  water-of- 
crystallization  content  than  the  'borax'  of  commerce,  so  that  when 
re-crystallized  to  borax,  the  resulting  product  has  an  increased  weight 
over  the  original  material.  These  deposits  are  being  opened  up  by  the 
Pacific  Coast  Borax  Company  in  southeastern  Kern  County. 

Refined  'borax'  (sodium  tetraborate)  is  used  in  making  the  enameled 
coating  for  cast-iron  and  steelware  employed  in  plumbing  fixtures, 
chemical  equipment,  and  kitchen  utensils.  It  is  also  a  constituent  of 
borosilicate  glasses  which  are  utilized  in  making  lamp  chimneys,  baking 
dishes,  and  laboratory  glassware.  Other  important  uses  of  borax  are 
in  the  manufacture  of  laundry  and  kitchen  soaps,  in  starch,  paper  siz- 
ing, tanning,  welding,  and  in  the  preparation  of  boric  acid,  which  is 
employed  as  an  antiseptic  and  in  preserving  meats.  Among  the  newer 
uses  for  borax  is  its  employment  in  the  preserving  of  citrus  fruits  by 
washing  them  in  a  solution  of  borax,  which  closes  the  pores  of  the  skin. 
The  application  of  this  process  is  increasing  in  California  and  Florida. 
Another  is  as  a  preservative  of  wood,  in  addition  to  which  borax,  being 
non-inflammable,  renders  it  fireproof. 

An  increased  foreign  demand  stimulated  an  increased  production  of 
this  material.  The  total  amount  exi^orted  from  the  United  States  was 
36,954  short  tons  valued  at  $2,422,144  compared  with  14,305  short  tons 
valued  at  $1,256,798  in  1926.  From  one  California  port  in  1927 
approximately  22,000  short  tons  of  borax  was  shipped  to  the  United 
Kingdom  and  continental  Europe. 

California  deposits  are  the  most  important  source  of  borax  in  the 
world,  and  that  this  material  can  be  mined  and  refined  at  a  low  cost, 
sup])lying  an  increasing  market,  is  shown  in  the  following  article  taken 
from  the  Engineering  and  Mining  Journal  :^ 

"New  aspects  in  the  present  situation  of  the  borax  industry  have  been  disclosed 
by  an  authority  as  the  result  of  the  recent  development  of  important  new  deposits 
of  borate  minerals  in  the  Kramer  district  in  southeast  Kern  County,  California. 

"The  new  mine  that  has  been  opened  by  the  Pacific  Coast  Borax  Company  in  the 
northwest  corner  of  Sec.  24,  T.  11  N.,  R.  S  W.,  and  the  extreme  northwest  corner 
of  Sec.  19  of  the  township  next  adjoining  on  the  east,  is  apparently  now  on  regnlar. 
production,  with  railroad  connections  established  and  shipping  the  new  kernite 
ore  in  large  quantities.  The  present  output  of  borate  ores  or  products  in  the  United 
States  is  approximately  as  follows  : 

Pacific  Coast  Borax  Co.  mine  near  Kramer,  Average  dail}/  shipment

Lake,  Cal.   1.5   tons  refined  borax 

Total    daily   production 3 SO  tons 

"The  total  production  represented  by  these  averages,  if  they  are  maintained 
throughout  this  year,  will  be  approximately  140,000  tons  of  borax  for  1928,  which  is 
probably   approximately  the  amount   of  present  market  requirements. 

"The  new  source  of  borate  mineral  at  Kramer  is  probably  the  most  available 
source  of  borax  that  the  world  has  ever  known,  in  quality  of  material,  massiveness, 
purity,  minability  of  the  deposit,  and  accessibility.  The  new  mineral  kernite  appar- 
ently exists  under  extremely  favorable  mining  conditions,  so  that  the  ore  can  appar- 
ently be  brought  to  the  surface  at  a  cost  of  less  than  $10  a  ton.  It  may  be  recalled 
that  the  kernite  ore  recovered  in  such  pure  form  as  indicated  by  the  present  opera- 
tions should  yield  more  than  its  equivalent  in  weight  of  commercial  borax,  and  that

only  the  simplest  refining  processes  are  required  to  transform  the  crude  material  as 
mined  into  the  commercial  product.  Therefore  it  is  entirely  likely  that  the  cost  of 
borax  may  be  cut  from  recent  quotations,  which  have  ranged  around  four  cents  a 
pound,  to  one-half  that  amount  or  even  less. 

"Another  interestin.e;  factor  may  also  have  an  important  Influence  in  the  produc- 
tion situation  and  marketing  of  this  product.  It  appears  that  an  important  exten- 
sion of  the  ricliest  part  of  these  deposits  lies  south  of  the  property  now  being  oper- 
ated and  this  new  deposit  is  evidently  under  independent  contn)l.  The  discovery  was 
made  by  borings  and  is  situated  about  tliree-fiuarters  of  a  mile  southwest  of  the 
•  original"  sliaft  in  the  northeast  corner  of  Sec.  24.  According  to  authentic  informa- 
tion these  borax  deposits  revealed  a  thick  section  of  particularly  pure  kernite  in  the 
new'  area  referred  to,  and  a  mining  shaft  is  being  rapidly  sunk  to  develop  this  new 
deposit.  The  material  which  may  ))e  developed  from  this  independent  operation 
promises  to  exert  an  important  intluence  with  tlie  Kramer  district." 

Total  Production  of  Borate   Materials  in  California. 

Borax  was  first  discovered  in  California  in  the  waters  of  Tuscan 
Springs  in  Tehama  County,  January  8,  1856.  Borax  Lake  in  Lake 
County  was  discovered  in  September  of  the  same  year  by  Dr.  John  A. 
Veach.  This  deposit  was  worked  in  1864-1868,  inclusive,  and  during 
that  time  produced  1,181,365  pounds  of  refined  borax.  The  bulk  of 
it  was  exported  by  sea,  to  New  York.  This  was  the  first  commercial 
output  of  this  salt  in  the  United  States,  and  California  is  still  today 
the  leading  American  producer  of  borax,  having  been  for  many  years 
the  sole  producer. 

Production  from  the  dry  lake  'playa'  deposits  of  Inyo  and  San 
Bernardino  counties  began  in  1873 ;  but  it  was  not  until  1887  that  the 
borax  industry  was  revolutionized  by  the  discovery  of  the  colemanite 
beds  at  Calico,  in  San  Bernardino  County,  and  later  similar  beds  in 
Inyo  and  Los  Angeles  counties.  The  colemanite  deposits  of  Ventura 
County  are  at  present  unworked,  owing  to  lack  of  transportation  facili- 
ties. Some  production  of  colemanite  has  been  made  from  deposits 
opened  up  in  Clarke  County,  Nevada. 

The  total  production  of  borate  materials  in  California  is  shown  in

120  MINERAL    INDUSTRY    OF    CALIFORNIA 

BROMINE 

The  first  commercial  production  of  bromine  and  bromine  compounds 
was  begun  during  1926  by  the  California  Chemical  Corporation  in  its 
plant  at  Chula  Vista,  San  Diego  County,  from  salt-works  bittern  waters. 
This  same  plant  has  been  recovering  magnesium  chloride  for  a  number 
of  years.  A  small  amount  of  bromine  was  also  reported  made  at  the 
similar  bittern-water  plant  of  the  Industrial  Chemical  Company  at 
Newark,  Alameda  County.  The  amounts  and  values  of  this  first  and 
second  years'  yields  of  bromine  in  California  are  concealed  under  the 
'Unapportioned'  item. 

A  large  part  of  the  bromine  output  of  the  United  States  is  not  sold 
as  bromine,  but  in  the  form  of  potassium  and  sodium  bromides  and 
other  salts.  The  principal  production  in  the  United  States  has  come 
from  bitterns  from  salt  wells  in  Michigan,  Ohio  and  West  Virginia. 

The  best  known  uses  of  bromine  are  its  application  in  the  form  of 
silver  bromide  in  photography  and  the  manufacture  of  ethyl  gasoline. 
Bromine,  as  such,  was  used  extensively  in  the  European  War  in  making 
asphyxiating  gases.  It  also  has  some  uses  in  medicine,  particularly  in 
the  treatment  of  nervous  diseases. 

CALCIUM    CHLORIDE

Calcium  chloride  is  hygroscopic,  that  is,  it  has  an  affinity  for  water. 
This  property  is  taken  advantage  of  by  utilizing  this  salt  as  a  drying 
agent.  It  is  also  sprinkled  on  dirt  roads  and  playgrounds  to  keep  down 
dust  by  absorbing  moisture.  In  refrigerating  machinery  for  ice  fac- 
tories, meat-packing  houses  and  cold-storage  warehouses,  a  calcium- 
chloride  solution  is  stated  to  have  some  advantages  over  salt  brine.  In 
fire  buckets  this  solution  has  an  advantage  over  pure  water,  in  that  it 
has  a  lower  freezing  point,  does  not  corrode  metal,  and  tends  to  keep 
the  buckets  full  due  to  its  absorbing  moisture  from  the  atmosphere. 
Powdered  calcium  chloride  is  used  in  drying  gases,  fruits  and  vege- 
tables. 

Total  Calcium  Chloride  Production  of  California. 

Commercial  production  of  calcium  chloride  in  California  was  first 
reported  to  the  State  Mining  Bureau  in  1921,  from  two  plants  in  San 
Bernardino  County,  being  obtained  as  a  by-product  in  the  refining  of 
salt  from  deposits  in  certain  of  the  desert  dry  lakes.  In  1922-1924, 
there  was  only  a  single  operator,  so  that  the  annual  details  are  concealed 
under  the  'unapportioned'  item.

The  1927  production  of  magnesium  salts  in  California  is  concealed 
under  'unapportioned.'  This  was  nearly  all  chloride,  sold  for  use  in 
magnesite  stucco  and  cement  mixtures  (Sorel  cement),  also  some  for 
'road  liquor.'  It  was  in  part  marketed  in  the  liquid  form  testing 
34°-36°  Baume,  and  in  part  as  dry  crystals,  and  was  prepared  from 
residual  bitterns  at  salt  plants  in  Alameda  and  San  Diego  counties. 
The  sulphate  marketed  was  utilized  for  medicinal  and  bath  purposes. 

"With  the  use  of  magnesite  cement  and  stucco  coming  -more  into  prom- 
inence in  building  construction  on  the  Pacific  Coast,  the  demand  for 
magnesium  chloride  is  increasing  here ;  but  the  domestic  article  has  to 
meet  the  competition  of  the  cheaper,  imported  German  chloride. 

The  average  value  reported  for  the  chloride  produced  in  California 
in  1927  was  approximately  $19  per  ton,  f.  o.  b.  plant. 

Total  Production  of  Magnesium  Salts  in  California. 

Commercial  production  of  magnesium  chloride  in  California  was 
begun  in  1916  by  some  of  the  salt  companies,  from  the  residual  bitterns 
obtained  during  the  evaporation  of  sea  water  for  its  sodium  chloride. 
In  addition,  some  magnesium  sulphate,  or  'epsom  salts'  is  also  made, 
annually,  but  in  smaller  amount. 

The  total  production  of  magnesium  salts  in  California,  since  the

Nitrates  of  sodium,  potassium  and  calcium  have  been  found  in  various 
places  in  the  desert  regions  of  the  state,  but  no  deposit  of  commercial 
value  has  been  developed  as  yet.  It  is  hoped  that  a  closer  search  may 
some  day  be  rewarded  by  workable  discoveries.  At  present  the  princi- 
pal commercial  source  of  nitrates  is  the  Chilean  saltpeter  (sodium 
nitrate)  deposits  in  South  America. 

The  fixation  of  atmospheric  nitrogen  electrically  has  been  accom- 
plished successfully  in  Germany  and  Scandinavia.  The  possibilities  of

During  1927,  a  total  of  67,340  tons  of  potash  salts  of  all  grades  was 
produced  in  California,  valued  at  $1,952,852,  compared  with  32,884  tons 
and  $812,285  in  1926.  This  was  in  part  chloride  and  part  from  distil- 
lery slops  char.  The  quality  of  the  product  averaged  60%  equivalent 
KoO  content;  and  the  material  was  sold  principally  for  fertilizer 
manufacture. 

Imports  of  crude  potash  minerals  and  salts  into  the  United  States 
in  1927,  according  to  the  U.  S.  Bureau  of  Foreign  and  Domestic  Com- 
merce, amounted  to  623,109  long  tons,  valued  at  $13,423,925,  compared 
with  815,715  tons  and  $14,122,699  in  1926.  These  materials  consisted 
mainly  of  'manure  salts,'  crude  chloride  (muriate)  and  sulphate,  and 
kainite,  all  of  which  are  admitted  duty-free. 

Quotations  have  recently  ranged  from  $46  per  ton  c.i.f.  Atlantic  and 
Gulf  ports,  for  high-grade  sulphate  (90%-95%),  to  $35  per  ton  for 
muriate  (80%-85%),  and  $19  for  manure  salts  (30%). 

Other  uses  for  potash  salts,  besides  those  noted  above,  are  in  the 
manufacture  of  the  best  liquid  soap  and  some  higher-grade  cake  soaps, 
of  some  finer  grades  of  glass,  and  in  matches.  The  chemical  require- 
ments include  tanning,  dyeing,  metallurgy,  electroplating,  photography 
and  medicine. 

Total  Production  of  Potash  in  California. 

Potash  production  began  commercially  in  California  in  1914,  with  a 
small  yield  from  kelp.  The  bulk  of  the  output  comes  from  deposits  of 
potash-bearing  residues  and  brines  in  the  old  lake  beds  of  the  desert 
regions,  particularly  Searles  Lake,  San  Bernardino  County.  A  small 
amount  is  made  annually  from  salt-works  bitterns,  and  for  a  time  there 
was  some  from  Portland  cement  dust.  Some  also  is  obtained  from 
molasses  distillery-slops  char. 

The  annual  amounts  and  value  of  these  potash  materials,  since  their 
beginning  in  California  in  1914,  are  shown  by  the  following  table :

Most  of  the  salt  production  in  California  is  obtained  by  evaporating 
the  water  of  the  Pacific  Ocean,  plants  being  located  on  the  shores  of 
San  Francisco,  Monterey,  and  San  Diego  bays,  and  at  Long  Beach. 
Additional  amounts  are  derived  from  lakes  and  lake  beds  in  the  desert 
regions,  mainly  in  Kern  and  San  Bernardino  counties.  A  small  amount 
of  valuable  medicinal  salts  is  obtained  by  evaporation  of  the  water  of 
Lake  Mono,  Mono  County.

county  and  trona  ('sesqui-carbonate,'  a  double  salt  of  NaoCOg  and 
NaHCOg)  from  Searles  Lake,  San  Bernardino  County.  There  were 
no  shipments  of  salt  cake  (sulphate)  from  the  Carrizo  Plains,  San  Luis 
Obispo  County  in  1927.  The  total  amounted  to  62,571  tons,  valued  at 
$1,478,239,  beins;  a  slight  decrease  in  quantity  but  an  increase  in  value 
compared  with  the  1926  figures  of  63,333  tons  and  $1,305,802. 

The  dense  ash  and  bicarbonate  were  used  mainly  in  the  manufacture 
of  soap,  glass,  sugar  refining,  and  chemicals ;  and  the  trona  for  metal- 
lurgical purposes. 

Sodium  compounds  to  some  extent  replace  potassium  compounds,  in 
glass  and  soap  making,  in  photography,  in  match  making,  in  tanning, 
sugar  refining,  and  in  the  manufacture  of  cyanide  for  extracting  gold 
and  silver  from  their  ores.

CHAPTER  SEVEN 

BY  COUNTIES 

Introductory. 

The  State  of  California  includes  a  total  area  of  158,297  square  miles, 
of  which  155,652  square  miles  are  of  land.  The  maximum  width  is 
235  miles,  the  minimum  148  miles,  and  the  length  from  the  northwest 
corner  to  the  southeast  corner  is  775  miles.  The  state  is  divided  into 
fifty-eight  counties.  The  1920  census  figures  show  a  total  population 
for  California  of  3,437,709.  A  1927  estimate  by  the  State  Controller 
places  the  figure  that  year  at  5,398,457.  Minerals  of  commercial  value 
exist  in  every  county,  and  during  1927  some  active  production  was 
reported  to  the  State  Division  of  Mines  and  Mining  from  all  of  the 
fifty-eight. 

Rank  of  Counties  in  Mineral  Yield,  1927. 

Of  the  first  ten  counties,  in  point  of  total  output  for  1927,  the  first 
four,  Los  Angeles,  Kern,  Orange,  Ventura,  owe  their  position  mainly  to 
petroleum,  as  does  also  Fresno  (sixth).  Los  Angeles,  due  to  its  oil, 
leads  all  the  others,  being  credited  with  36%  of  the  entire  state's  total 
value  for  1927,  having  passed  Kern  in  1923,  which  led  for  many  years. 
San  Bernardino  (fifth)  owes  its  place  chiefly  to  cement,  silver,  potash, 
borax,  mineral  water,  and  tungsten;  Riverside  (seventh)  to  cement, 
stone,  brick  and  tile;  Yuba  (eighth)  to  gold;  Santa  Cruz  (ninth)  to 
cement;  Plumas  (tenth)  to  copper.  Twenty-four  counties  have  each  a 
total  in  excess  of  a  million  dollars  in  1927.  Cement  is  an  important 
item  in  nine  of  these  counties,  gold  in  four,  and  miscellaneous  stone, 
granite,  and  soda  in  one  each.  In  the  point  of  variety  and  diversity, 
San  Bernardino  County  led  all  others  in  1927,  with  a  total  of  23  differ- 
ent mineral  products  on  its  commercial  list,  followed  by  Los  Angeles 
with  20 ;  San  Diego  with  19 ;  Kern  and  Riverside  with  17  each ;  Inyo 
with  13 ;  Butte,  12 ;  Calaveras,  Monterey,  Santa  Barbara  and  Shasta 
with  11  each.  The  counties  with  their  mineral  resources,  production 
for  1927,  etc.,  are  considered  in  detail  in  the  following  paragraphs.

Alameda  County,  while  in  no  sense  one  of  the  'mining  counties,' 
comes  twelfth  on  the  list  with  a  value  of  mineral  products  for  1927  of 
$2,577,787,  a  decrease  from  the  1926  total,  which  was  $3,158,474. 

The  mineral  resources  of  this  county  include  asbestos,  brick,  chro- 
mite,  clay,  coal,  copper,  g'old,  limestone,  quartz  crystals,  glass-sand,

Location:  On  eastern  border  of  state,  south  of  Lake  Tahoe. 

This  county  lies  just  south  of  Lake  Tahoe,  in  the  high  Sierra  Nevada. 
Transportation  is  by  auto,  wagon,  or  mule  back,  and  facilities  in  general 
are  lacking  to  promote  development  work. 

The  mineral  resources  of  this  section  are  varied  and  the  country  has 
not  yet  been  thoroughly  jn-ospected.  Occurrences  of  barium,  copper, 
gold,  gypsum,  lead,  limestone,  pyrite,  rose  quartz,  silver,  tourmaline, 
and  zine  have  been  noted  liere. 

Commercial  production  for  1927  was  as  follows,  being  an  increase 
from  $450  in  1926 :

AMADOR 

Land  area:  601  square  miles. 

Population:  7793   (1920  census). 

Location:  East-central  part  of  state — Mother  Lode  District. 

The  value  of  Amador  Countj'^'s  mineral  production  decreased  from 
$2,451,500  in  1926  to  $2,207,798,  placing  it  number  sixteen  on  the  list 
of  counties  in  the  state  as  regards  total  value  of  mineral  substances 
marketed.     The  decrease  was  due  mainly  to  gold. 

Although  having  an  output  consisting  of  nine  different  minerals,  the 
leading  product,  gold,  makes  up  approximately  87%  of  the  total  value 
for  the  year. 

Amador  at  one  time  led  the  state  in  gold  production,  though  exceeded 
in  1920-1923  and  in  1926-1927  by  Yuba  and  Nevada  counties,  but  in 
1925  by  Yuba  County  only.

Land  area:  1027  square  miles. 

Popidation:  6183  (1920  census). 

Location:  East-central  portion  of  state — Mother  Lode  district. 

Calaveras  County  reported  production  of  eleven  different  minerals, 
valued  at  $1,608,714,  during  the  year  1927,  as  compared  with  the  1926 
output  of  $1,809,772.  Cement,  gold,  copper  and  stone  are  the  chief 
mineral  substances.  In  regard  to  total  value  of  mineral  output,  Cala- 
veras stands  twenty-second  among  the  counties  of  the  state  for  1927,

COLUSA 

Land  area:  1140  square  miles. 
Population:  9920  (1920  census). 
Location:  Sacramento  Valley. 

Colusa  County  lies  largely  in  the  basin  of  the  Sacramento  Valley. 
Its  western  border,  however,  rises  into  the  foothills  of  the  Coast  Range 
of  mountains,  and  its  mineral  resources — largely  undeveloped — include 
coal,  chromite,  copper,  gypsum,  manganese,  mineral  water,  pyrite, 
quicksilver,  sandstone,  miscellaneous  stone,  sulphur,  and  in  some  places 
traces  of  gold  and  silver. 

The  value  of  the  1927  production  was  $13,207,  a  decrease  from  the 
1926  figures  of  $91,194,  giving  it  fifty-fourth  place,  and  was  as  follows:

CONTRA  COSTA 

Land  area:  714  square  miles. 
Population:  53,889  (1920  census). 
Location:  East  side  of  San  Francisco  Bay. 

Contra  Costa,  like  Alameda  County,  lies  on  the  eastern  shore  of  San 
Francisco  Bay,  and  is  not  commonly  considered  among  the  mineral 
producing  counties  of  the  state.  It  stands  seventeenth  on  the  list  in 
this  respect,  however,  with  an  output  valued  at  $2,172,756  for  the 
calendar  year  1927.  Various  structural  materials  make  up  the 
chief  items,  including  brick,  cement,  limestone,  and  miscellaneous  stone. 
Among  the  others  are  asbestos,  clay,  coal,  gypsum,  manganese,  mineral 
water,  and  soapstone. 

Commercial  production  for  1927  was  as  follows : 

Substance  Value 

Brick  and  hollow  building  tile $303,302 

Stone,    miscellaneous    816,140 

Other  minerals  * 1,053,314

DEL   NORTE 

Land  area:  1024  square  miles. 
Population:  2759  (1920  census). 
Location:  Extreme  northwest  corner  of  state. 
Transportation:  Motor,    wagon    and    mule    back;    steamer    from 
Crescent  City. 

Del  Norte  almost  rivals  Alpine  County  in  regard  to  inaccessibility. 
Like  the  latter  county  also,  given  transportation  and  kindred  facilities, 
this  portion  of  the  state  presents  a  field  for  development  along  mining 
lines  especially.  Its  chief  mineral  resources,  largely  untouched,  are 
chromite,  copper,  gems,  gold,  iron,  platinum  group,  silver,  and  miscel- 
laneous stone. 

The  1927  output  was  a  decrease  from  the  figure  of  $70,464  in  1926,

El  Dorado  County,  which  contains  the  locality  where  gold  in  Cali- 
fornia was  first  heralded  to  the  world,  comes  forty-fourth  on  the  list 
of  counties  ranked  according  to  the  value  of  their  total  mineral  produc- 
tion during  the  year  1927.  In  addition  to  the  segregated  figures  here 
given,  a  large  tonnage  of  limestone  is  annually  shipped  from  El  Dorado 
for  use  in  cement  manufacture,  and  whose  value  is  included  in  the 
state  total  for  cement.  The  decrease  from  the  1926  figure  of  $302,086 
was  due  to  limestone.

Location:  South-central  portion  of  state. 

Fresno  County,  sixth  in  importance  as  a  mineral  producer  among  the 
counties  of  California,  reported  an  output  for  1927  of  nine  mineral 
substances  with  a  total  value  of  $7,547,216,  an  increase  from  the 
reported  1926  production,  which  was  worth  $6,699,928. 

The  bulk  of  the  above  is  derived  from  the  petroleum  production  of 
the  Coalinga  field,  with  miscellaneous  stone  also  important. 

The  mineral  resources  of  this  county  are  many,  and,  aside  from  crude 
oil,  are  in  the  main  not  fully  developed.  They  include  asbestos,  barytes,

Location:  West  side  of  Sacramento  Valley. 

Glenn  County,  standing-  forty-seventh,  owes  its  position  among  the 
mineral-producing  counties  of  the  state  mainly  to  the  presence  of  large 
deposits  of  sand  and  gravel  which  are  annually  worked,  the  product 
being  used  for  railroad  ballast,  etc.  In  1917  and  1918,  chromite  was 
also  an  important  item.  In  the  foothills  in  the  western  portion  of  the 
county,  deposits  of  chromite,  copper,  manganese,  sandstone,  and  soap- 
stone  have  been  found.

Population:  7031   (1920  census). 

Location:  Lies  on  eastern  border  of  state,  north  of  San  Bernardino 
County. 

Inyo,  the  second  largest  county  in  the  state,  and  containing  less  than 
one  inhabitant  per  square  mile,  is  extremely  interesting  from  a  mineral- 
ogical  point  of  view.  It  is  noted  because  of  the  fact  that  within  its 
borders  are  located  both  the  highest  point,  Mount  Whitney  (elevation 
14,502  feet),  and  the  lowest  point.  Death  Valley  (elevation  290  feet 
below  sea  level),  in  the  United  States.  In  the  higher  mountainous 
sections  are  found  many  vein-forming  minerals,  and  in  the  lake  beds  of 
Death  Valley  saline  deposits  exist. 

Inyo's  mineral  production  during  the  year  1927  reached  a  value  of 
$2,519,834,  standing  thirteenth  among  the  counties  of  the  state  in  this 
respect.  Thirteen  different  mineral  substances  were  produced.  The 
1926  production  value  was  $2,835,834.  Its  mineral  resources  include 
antimony,  asbestos,  barytes,  borates,  copper,  dolomite,  gems,  gold,

years  stood  preeminent  among  all  counties  of  California  in  the  value  of 


132  MINERAL    INDUSTRY    OF    CALIFORNIA 

its  mineral  output,  the  exact  figures  for  1927  being  $64,729,488.  Kern 
was  surpassed  by  both  Los  Angeles  and  Orange  counties  in  1923,  but  by 
Los  Angeles,  only,  in  1924-1927,  for  which  petroleum  also  is  respon- 
sible. The  1926  mineral  output  for  this  county  was  worth  $83,556,074. 
The  decrease  was  due  to  a  smaller  quantity  and  lower  prices  of  crude 
oil.    During  1927  seventeen  different  mineral  substances  were  produced. 

Among  the  mineral  resources,  developed  and  undeveloped,  of  this 
section  are  antimony,  asphalt,  borax,  brick,  clay,  cement,  copper,  feld- 
spar, fuller's  earth,  gems,  gold,  gypsum,  iron,  lead,  limestone,  magne-

■  Lassen  County  is  one  of  the  only  partly-developed  sections  of  Cali- 
fornia. Since  about  1912  a  railroad  traversing  the  county  north  and 
south  has  been  in  operation,  thus  affording  opportunity  for  develop- 
ment along  mineral  and  other  lines. 

Among  the  mineral  resources  of  tliis  county  are  copper,  gems,  gyp- 
sum, gold,  silver,  and  sulphur.  In  the  past,  some  gold  had  been  pro- 
duced, but  not  for  some  years,  until  1921,  when  the  yield  again  became 
important.  In  fifty-first  place,  commercial  production  for  1927  was  as

amounted  in  value  to  $131,832,441,  as  compared  with  the  1926  output 
worth  $194,358,926.  This  accounts  for  36%  of  the  entire  state's  total 
for  1927,  and  ranks  Los  Angeles  County  first  in  the  state  as  a  mineral 
producer,  having  in  1923  passed  Kern  County,  which  had  been  leading 
for  several  years.  The  decrease  in  1927  was  due  to  lower  petroleum 
prices,  and  a  slight  decrease  in  quantity. 

Its  output  of  brick  and  tile  was  over  three  million  dollars,  and  that 
of  petroleum  amounted  to  over  one  hundred  fourteen  million  dollars.

in  1918-1921,  also  1923.  In  1922  and  1924,  Nevada  led,  but  dropped  to 
third  place  in  1925,  regaining  second  in  1926.  Nevada  County  stands 
fifteenth  on  the  list  in  regard  to  value  of  its  total  mineral  output  for 
1927  with  a  figure  of  $2,213,709  as  compared  with  the  1926  production 
worth  $3,240,211.  The  decrease  is  due  mainly  to  miscellaneous  stone, 
but  in  part  to  gold.

Location:  Southwestern  portion  of  state,  bordering  Pacific  Ocean. 

Orange  County  is  one  of  the  many  in  California  which  on  casual 
inspection  appears  to  be  anytliing  but  a  mineral  producing  section.  It 
stood  for  several  years,  however,  as  the  second  county  in  the  state  in 
regard  to  the  total  value  of  mineral  output,  on  account  of  its  highly 
productive  oil  fields.  It  was  passed  in  1922  by  Los  Angeles,  the  credit 
for  which  is  also  due  to  oil,  and  in  turn  Orange  passed  Kern  County  in 
1923,  but  dropped  back  to  third  in  1924-1926. 

This  county  shows  a  mineral  production  for  1927  of  $60,547,041, 
compared  to  the  1926  output,  worth  $63,223,082,  the  decrease  due  to 
lower  petroleum  prices.  Orange  passed  Shasta  County  in  1917,  which 
previously  for  a  number  of  years  had  exceeded  all  other  counties  in 
California,  except  Kern. 

Aside  from  the  substances  actually  produced  and  noted  in  the  table 
below,  coal,  gypsum,  iron,  infusorial  earth,  sandstone,  and  tourmaline

pared  with  the  1926  production  worth  $2,886,144,  the  decrease  beingj 
due  to  zinc,  and  in  part  to  gold. 

The  marked  decrease  since  1918  is  due  to  the  falling  off  in  the  output^ 
of  copper,  the  large  plants  of  the  Mammoth  and  Mountain  copper  com- 
panies being  shut  down.  Not  taking  petroleum  into  account,  Shasta 
for  a  number  of  years  led  all  of  the  counties  by  a  wide  margin,  but  in 
1919-1923  was  passed  by  San  Bernardino,  Plumas,  Yuba,  Inyo,  Sacra-

Location:  Southwestern    portion    of   state,    bordering   on    Pacific 
Ocean. 

Ventura  is  the  fourth  county  in  the  state  in  respect  to  the  value  of 
its  mineral  production  for  1927,  the  exact  figure  being  $30,995,379,  as 
^compared  with  the  output  for  1926  worth  $30,208,369,  the  increase 
)eing  due  to  natural  gas  and  miscellaneous  stone  notwithstanding  a 
^cut  in  petroleum  prices.

YOLO 

Land  area:  1017  square  miles. 
Popidation:  17,105  (1920  census). 

Location:  Sacramento  Valley,  bounded  by  Sutter  on  the  east  and 
Colusa  on  the  north. 

The  mineral  production  from  Yolo  County  during  the  year  1927 
consisted  entirely  of  miscellaneous  stone,  valued  at  $17,895,  ranking  it 
in  fifty-third  place.  Deposits  of  undetermined  value  of  iron  and  sand- 
stone have  been  discovered  within  the  confines  of  this  county.  Quick- 
silver has  also  been  produced. 

YUBA 

Land  area:   639  square  miles. 
Popidation:  10,375  (1920  census). 

Location:  Lies   west   of   Sierra   and   Nevada   counties;   south   of 
Plumas. 

Yuba  is  eighth  of  the  mineral  producing  counties  of  the  state,  and 
first  in  regard  to  gold  output  for  1925-1927,  having  passed  Nevada  and 
Amador  counties  in  that  metal.  Iron  and  clay  deposits  have  been 
reported  in  this  county  aside  from  the  following  commercial  production 
shown  for  the  year  1927.  The  increase  over  the  1926  figure  of  $2,921,083 
was  due  mainly  to  gold  obtained  by  the  dredgers,  which  also  yield 
silver  and  platinum.  The  1921  dredge  yield  of  gold  was  a  record  for 
the  county.

CHAPTER    EIGHT 


TOTAL  RECORDED  MINERAL  PRODUCTION  BY  COUNTIES 


Herein  in  the  tabulations  following  we  present  the  total  mineral 
yield  of  each  county  of  the  state  from  the  earliest  available  records  to 
and  including  1927.  These  tables  were  previously  printed  in  ]\riNiNG 
In  California,  November,  1922,  Chapter  of  Report  XVIII  of  the  State 
Mineralogist,  which  included  the  data  to  the  end  of  1921. 

In  a  number  of  cases  it  is  known  that  there  were  productions  of 
specific  minerals  in  the  years  previous  to  the  earliest  years  shown  in 
these  tabulations ;  but  unfortunately,  there  are  few  detailed  or  accurate 
records  showing  county  segregations  prior  to  1894  when  compilation  of 
the  statistical  records  of  the  California  State  Mining  Bureau  began. 
For  gold  and  silver,  the  published  reports  of  the  U.  S.  Geological  Survey 
and  the  Director  of  the  Mint  give  county  segregations  back  to  1880 ;  but, 
prior  to  that  year,  we  have  only  the  state  total  annually.  In  the  case 
of  quicksilver,   there  are   authentic  records  for  all  of  the  important 

^ mines,  from  which  we  have  compiled  county  tables  for  the  early  years. 

The   "unapportioned"   column  is  necessitated   by  the  fact  that  in 

lany  cases  there  is  but  a  single  operator  or  mine  producing  a  given 

[mineral  in  the  county.    As  it  is  the  policy  of  the  Division  of  Mines  and 
Mining  not  to  reveal  the  individual's  private  business  without  his  con- 

[sent,  we  combine  the  values  of  such  products.

•There  are  no  records  of  annual  mineral  production  for  the  period  of  1865-1876,  but  there  was  a  small  annual  gold  produc- 
tion from  shallow  placers  before  this,  and  these  placers  have  no  doubt  yielded  considerable  gold  never  reported.  The  same 
observation  applies  to  a  number  of  small  quicksilver  properties  worked  in  the  '70's.

294  MINERAL  INDUSTRY  OF  CALIFORNIA 


PUBLICATIONS  OF  THE  DIVISION  OF 
MINES  AND  MINING 

During  the  past  forty-eight  years,  in  carrying  out  the  provisions  of 
the  organic  act  creating  the  former  California  State  Mining  Bureau, 
there  have  been  published  many  reports,  bulletins  and  maps  which  go 
to  make  up  a  library  of  detailed  information  on  the  mineral  industry  of 
the  state,  a  large  part  of  which  could  not  be  duplicated  from  any  other 
source. 

One  feature  that  has  added  to  the  popularity  of  the  publications  is 
that  many  of  them  have  been  distributed  without  cost  to  the  public,  and 
even  the  more  elaborate  ones  have  been  sold  at  a  price  which  barely 
covers  the  cost  of  printing. 

Owing  to  the  fact  that  funds  for  the  advancing  of  the  work  of  this 
department  have  often  been  limited,  many  of  the  reports  and  bulletins 
mentioned  were  printed  in  limited  editions  which  are  now  entirely 
exhausted. 

Copies  of  such  publications  are  available,  however,  in  the  office  of 
the  Division  of  Mines  and  Mining,  in  the  Ferry  Building,  San  Fran- 
cisco; New  Orpheum  Building,  Los  Angeles;  State  Office  Building, 
Sacramento;  Redding;  Santa  Maria;  Santa  Paula;  Coalinga;  Taft; 
Bakersfield.  They  may  also  be  found  in  many  public,  private  and 
technical  libraries  in  California  and  other  states,  and  foreign  countries. 

A  catalog  of  all  publications  from  1880  to  1917,  giving  a  synopsis  of 
their  contents,  is  issued  as  Bulletin  No.  77. 

Publications  in  stock  may  be  obtained  by  addressing  any  of  the  above 
offices  and  enclosing  the  requisite  amount  in  the  case  of  publications 
that  have  a  list  price.  Only  coin,  stamps  or  money  orders  should  be 
sent,  and  it  will  be  appreciated  if  remittance  is  made  in  this  manner 
rather  than  by  personal  check. 

The  prices  noted  include  delivery  charges  to  all  parts  of  the  United 
States.  Money  orders  should  be  made  payable  to  the  Division  of  Mines 
and  Mining. 

Note. — The  Division  of  Mines  and  Mining  frequently  receives  requests  for  some 
of  the  early  Reports  and  Bulletins  now  out  of  print,  and  it  will  be  appreciated  if 
parties  having  such  publications  and  wishing  to  dispose  of  them  will  advise  this 
office.
